From stat().st_mtime to datetime?

You can use datetime.datetime.fromtimestamp, i.e.

from datetime import datetime, timezone
...
stat_result = path.stat()
modified = datetime.fromtimestamp(stat_result.st_mtime, tz=timezone.utc)
print('modified', modified)

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')
