From stat().st_mtime to datetime?

Question

What is the most idiomatic/efficient way to convert from a modification time retrieved from stat() call to a datetime object? I came up with the following (python3):

from datetime import datetime, timedelta, timezone
from pathlib import Path

path = Path('foo')
path.touch()
statResult = path.stat()
epoch = datetime(1970, 1, 1, tzinfo=timezone.utc)
modified = epoch + timedelta(seconds=statResult.st_mtime)
print('modified', modified)

Seems round a bout, and a bit surprising that I have to hard code the Unix epoch in there. Is there a more direct way?

Answer 1

Try datetime.fromtimestamp(statResult.st_mtime)

e.g.

import datetime

mod_timestamp = datetime.datetime.fromtimestamp(path.getmtime(<YOUR_PATH_HERE>))

Answer 2

This works for me if you want a readable string:

import datetime
mtime = path.stat().st_mtime
timestamp_str = datetime.datetime.fromtimestamp(mtime).strftime('%Y-%m-%d-%H:%M')
