jinja2 how to remove microsecond in datetime

Question

In a Jinja2 template I want to display the last login:

Last Login: {{ user.last_seen }}

last_seen is supposed to be a datetime obj

Answer 1

You are using the default string formatting of a datetime object, which is essentially the same as calling datetime.isoformat(' '), a format that includes the microseconds component.

If you want a different format, then do so explicitly, using the datetime.datetime.strftime() method:

Last Login: {{ user.last_seen.strftime('%Y-%m-%d %H:%M:%S') }}

Alternatively, produce a new datetime object with the microseconds component set to 0, then interpolate that:

Last Login: {{ user.last_seen.replace(microsecond=0) }}
