Day view table is always empty on FreeBSD

On FreeBSD strptime does not convert year value when time value is incomplete. For example, with time pattern %Y%m%dT%H%M%S, and time string is 20220208T090000 then this will be converted to 2022-02-08 09:00:00, but if time string is 20220208 then this is converted to 1900-02-08. This behaviour affects week view, where week view does not show any events. Probably there are some other affected places also. It seems to be FreeBSD 12.3 issue, with 11.x was day view table filled normally.
