问题:
In a Windows (Windows XP) batch script I need to format the current date and time for later use in files names, etc.
It is similar to Stack Overflow question How to append a date in batch files, but with time in as well.
I have this so far:
echo %DATE%
echo %TIME%
set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
echo %datetimef%
which gives:
28/07/2009
8:35:31.01
2009_07_28__ 8_36_01
Is there a way I can allow for a single digit hour in %TIME%, so I can get the following?
2009_07_28__08_36_01
回答1:
I ended up with this script:
set hour=%time:~0,2%
if "%hour:~0,1%" == " " set hour=0%hour:~1,1%
echo hour=%hour%
set min=%time:~3,2%
if "%min:~0,1%" == " " set min=0%min:~1,1%
echo min=%min%
set secs=%time:~6,2%
if "%secs:~0,1%" == " " set secs=0%secs:~1,1%
echo secs=%secs%
set year=%date:~-4%
echo year=%year%
:: On WIN2008R2 e.g. I needed to make your 'set month=%date:~3,2%' like below ::otherwise 00 appears for MONTH
set month=%date:~4,2%
if "%month:~0,1%" == " " set month=0%month:~1,1%
echo month=%month%
set day=%date:~0,2%
if "%day:~0,1%" == " " set day=0%day:~1,1%
echo day=%day%
set datetimef=%year%%month%%day%_%hour%%min%%secs%
echo datetimef=%datetimef%

If PowerShell is installed, then you can easily and reliably get the Date/Time in any format you'd like, for example:
for /f %%a in ('powershell -Command "Get-Date -format yyyy_MM_dd__HH_mm_ss"') do set datetime=%%a
move "%oldfile%" "backup-%datetime%"
Of course nowadays PowerShell is always installed, but on Windows XP you'll probably only want to use this technique if your batch script is being used in a known environment where you know PS is available (or check in your batch file if PowerShell is available...)
You may reasonably ask: why use a batch file at all if you can use PowerShell to get the date/time, but I think some obvious reasons are: (a) you're not all that familiar with PowerShell and still prefer to do most things the old-fashioned way with batch files or (b) you're updating an old script and don't want to port the whole thing to PS.

I usually do it this way whenever I need a date/time string:
set dt=%DATE:~6,4%_%DATE:~3,2%_%DATE:~0,2%__%TIME:~0,2%_%TIME:~3,2%_%TIME:~6,2%
set dt=%dt: =0%
This is for the German date/time format (dd.mm.yyyy hh:mm:ss). Basically I concatenate the substrings and finally replace all spaces with zeros.
Short explanation of how substrings work:
%VARIABLE:~num_chars_to_skip,num_chars_to_keep%
So to get just the year from a date like "29.03.2018" use:
%DATE:~6,4%
^-----skip 6 characters
^---keep 4 characters

I came across this problem today and solved it with:
SET LOGTIME=%TIME: =0%
It replaces spaces with 0s and basically zero-pads the hour.
After some quick searching I didn't find out if it required command extensions (still worked with SETLOCAL DISABLEEXTENSIONS).
回答7:
As has been noted, parsing the date and time is only useful if you know the format being used by the current user (for example, MM/dd/yy or dd-MM-yyyy just to name two). This could be determined, but by the time you do all the stressing and parsing, you will still end up with some situation where there is an unexpected format used, and more tweaks will be be necessary.
You can also use some external program that will return a date slug in your preferred format, but that has disadvantages of needing to distribute the utility program with your script/batch.
There are also batch tricks using the CMOS clock in a pretty raw way, but that is tooo close to bare wires for most people, and also not always the preferred place to retrieve the date/time.
Below is a solution that avoids the above problems. Yes, it introduces some other issues, but for my purposes I found this to be the easiest, clearest, most portable solution for creating a datestamp in .bat files for modern Windows systems. This is just an example, but I think you will see how to modify for other date and/or time formats, etc.
reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f
reg add "HKCU\Control Panel\International" /v sShortDate /d "yyMMdd" /f
@REM reg query "HKCU\Control Panel\International" /v sShortDate
set LogDate=%date%
reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f

The following may not be a direct answer but a close one?
set hour=%time:~0,2%
if "%hour:~0,1%" == " " set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__0%time:~1,2%_%time:~3,2%_%time:~6,2%
else set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
At least it may be inspiring.
回答9:
If you don't exactly need this format:
2009_07_28__08_36_01
Then you could use the following 3 lines of code which uses %date% and %time%:
set mydate=%date:/=%
set mytime=%time::=%
set mytimestamp=%mydate: =_%_%mytime:.=_%
Note: The characters / and : are removed and the character . and space is replaced with an underscore.
Example output (taken Wednesday 8/5/15 at 12:49 PM with 50 seconds and 93 milliseconds):
echo %mytimestamp%
Wed_08052015_124950_93

REM Assumes UK style date format for date environment variable (DD/MM/YYYY).
REM Assumes times before 10:00:00 (10am) displayed padded with a space instead of a zero.
REM If first character of time is a space (less than 1) then set DATETIME to:
REM YYYY-MM-DD-0h-mm-ss
REM Otherwise, set DATETIME to:
REM YYYY-MM-DD-HH-mm-ss

回答11:
The offset:length formatting supported with the SET command in Windows will not allow you to pad the 0 as you seem to be interested in.
However, you can code a BATCH script to check for the hour being less than 10 and
pad accordingly with a different echo string.
You will find some information on the SET command on this link.
You can also change to other programming methods to get here.
It is quite simple in unix bash (available with Cygwin on Windows) to just say,
date +%Y_%m_%d__%H_%M_%S
And, it always pads correctly.

This batch script will do exactly what the O.P. wants (tested on Windows XP SP3).
I also used that clever registry trick described by "jph" previously which IMHO is the simplest way of getting 100% consistent formatting of the date to "yyyy_MM_dd" on any Windows system new or old. The change to one Registry value for doing this is instantaneous temporary and trivial; it only lasts a few milliseconds before it is immediately reverted back.
Double-click this batch file for an instant demo, Command Prompt window will pop up and display your timestamp . . . . .

I tried the accepted answer and it works pretty well. Unfortunately the US Time Format appears to be H:MM:SS.CS, and the missing 0 on the front was causing parsing problems before 10 am. To get over this hurdle and also allow parsing of most any of the world time formats, I came up with this simple routine that appears to work quite well.
:ParseTime
rem The format of %%TIME%% is H:MM:SS.CS or (HH:MM:SS,CS) for example 0:01:23.45 or 23:59:59,99
FOR /F "tokens=1,2,3,4 delims=:.," %%a IN ("%1") DO SET /A "%2=(%%a * 360000) + (%%b * 6000) + (%%c * 100) + %%d"
GOTO :EOF
The nice thing with this routine is that you pass in the time string as the first parameter and the name of the environment variable you want to contain the time (in centiseconds) as the second parameter. For example:
CALL :ParseTime %START_TIME% START_CS
CALL :ParseTime %TIME% END_CS
SET /A DURATION=%END_CS% - %START_CS%

For a very simple solution for numeric date for use in filenames use the following code:

Split the results of the date command by slash, then you can move each of the tokens into the appropriate variables.

SET _Year=%%c
)
ECHO Month %_Month%

In situations like this use a simple, standard programming approach:
Instead of expending a huge effort parsing an unknown entity, simply save the current configuration, reset it to a known state, extract the info and then restore the original state. Use only standard Windows resources.
Specifically, the date and time formats are stored under the registry key
HKCU\Control Panel\International\ in [MS definition] "values": "sTimeFormat" and "sShortDate".
Reg is the console registry editor included with all Windows versions.
Elevated privileges are not required to modify the HKCU key
Prompt $N:$D $T$G
::Save current config to a temporary (unique name) subkey, Exit if copy fails
Set DateTime=
Set ran=%Random%
Reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp%ran%" /f
If ErrorLevel 1 GoTO :EOF
::Reset the date format to your desired output format (take effect immediately)
::Resetting the time format is useless as it only affect subsequent console windows
::Reg add "HKCU\Control Panel\International" /v sTimeFormat /d "HH_mm_ss" /f
Reg add "HKCU\Control Panel\International" /v sShortDate /d "yyyy_MM_dd" /f
::Concatenate the time and (reformatted) date strings, replace any embedded blanks with zeros
Set DateTime=%date%__%time:~0,2%_%time:~3,2%_%time:~6,2%
Set DateTime=%DateTime: =0%
::Restore the original config and delete the temp subkey, Exit if restore fails
Reg copy "HKCU\Control Panel\International-Temp%ran%" "HKCU\Control Panel\International" /f
If ErrorLevel 1 GoTO :EOF
Reg delete "HKCU\Control Panel\International-Temp%ran%" /f
Simple, straightforward and should work for all regions.
For reasons I don't understand, resetting the "sShortDate" value takes effect immediately in
a console window but resetting the very similar "sTimeFormat" value does NOT take effect
until a new console window is opened. However, the only thing changeable is the delimiter -
the digit positions are fixed.Likewise the "HH" time token is supposed to prepend leading zeros but it doesn't.
Fortunately, the workarounds are easy.

Using % you will run into a hex operation error when the time value is 7-9. To avoid this, use DelayedExpansion and grab time values with !min:~1!
An alternate method, if you have PowerShell is to call that:
for /F "usebackq delims=Z" %%i IN (`powershell Get-Date -format u`) do (set server-time=%%i)
{var%20f='http://v.t.sina.com.cn/share/share.php?appkey=1515056452',u=z||d.location,p=['&url=',e(u),'&title=',e(t||d.title),'&source=',e(r),'&sourceUrl=',e(l),'&content=',c||'gb2312','&pic=',e(p||'')].join('');function%20a(){if(!window.open([f,p].join(''),'mb',['toolbar=0,status=0,resizable=1,width=440,height=430,left=',(s.width-440)/2,',top=',(s.height-430)/2].join('')))u.href=[f,p].join('');};if(/Firefox/.test(navigator.userAgent))setTimeout(a,0);else%20a();})(screen,document,encodeURIComponent,'','','https://img.manongdao.com/sparkler-677774__340.jpg', '推荐 只靠听说 的文章《Format date and time in a Windows batch script》','https://www.manongdao.com/article-12335.html','页面编码gb2312|utf-8默认gb2312'));){kind=link}
