View all issues with WP status.
The current specification of the
function does not cover the behaviour in the situation when
value is not
ok(). To illustrate the sentence from
188.8.131.52 [time.cal.ymdlast.members] p13:
dayrepresenting the last day of the (
month) pair represented by
is unclear in the situation when
month member has
!ok value, e.g. what is last day of 14th month of 2019.
ymdl.day()(and by consequence conversion to
local_days) unspecified if
false. This make is consistent with rest of the library, that produces unspecified values in similiar situation, e.g.: 184.108.40.206 [time.cal.ymd.members] p18, 220.127.116.11 [time.cal.ymwd.members] p19, 18.104.22.168 [time.cal.ymwdlast.members] p14.
