The struct_time type does not include information about what timezone it
is in.

You can use datetime.datetime (e.g. datetime.datetime.fromtimestamp(40 *
365 * 86400,datetime.timezone.utc) - the datetime.datetime class has a
strftime method.

You should be aware that %F and %T are not portable and won't work on
windows for example.
