Re: [PATCH 1/1] Fix date checking in case if time was not initialized.

quoted

So is_date() always return negative result for the text string where
date is placed before time like '2008-02-14 20:30:45'.

Yes, it returns this -1 on other platforms, but...

It must fail on
other platforms as well.

It also fails under Linux, but real problem is not here, it is just an
unoptimal date parser.

... the input '2008-02-14 20:30:45' still parses fine for others
(including me).  That is what is puzzling.
A shot in the dark: perhaps your time_t is unsigned?

Yeah, it was a headshot :) It really due to unsigned time_t. I will
send two patches right now with fixes regarding unsigned time_t
comparison.
