Invalid time strings are allowed

[Maximkaaa]

This strings are parsed without an error, even thought they should be invalid according to the GNU docs (and GNU date produces an error for them):

# If am/pm is used, min hour value must be 1
00:00:00am
00:00:00pm

# Either am/pm or time correction can be used, but not both
10:59am+01

Interesting observation, thanks for reporting.

I believe this one is fixed by #169

Re-opening this issue because

# Either am/pm or time correction can be used, but not both
10:59am+01

is not fixed yet.
