How can I make the history command display the date and time information in addition to the command line?

The history of executed commands is stored by your shell. Try adding something like this to you ~/.bashrc

export HISTTIMEFORMAT="%m/%d - %H:%M:%S: "

It will change the HISTTIMEFORMAT variable and bash will store a timestamp in its history accordingly. Then your history will look like this

487  08/16 - 16:12:01: cd Downloads
488  08/16 - 16:12:04: ls -a
489  08/16 - 16:12:37: cat README | less
490  08/16 - 16:12:58: pkg-config --list-all | grep webkit
491  08/16 - 16:13:04: history

Available identifiers are

%d - Day
%m - Month
%y - Year
%T - Time
%H - Hours
%M - Minutes
%S - Seconds
