Log Message:
POSIX requires that when converting 2 digit year representations to
actual specific years, values from 69-99 be treated as 20th century,
and values from 0-68 be treated as 21st century. This allows for those
unfortunate enough to reside in a timezone west of Greenwich to convert
the epoch (or a time very close to it) to text, write that with just two
digits, and correctly convert it back to a time near the epoch, rather
than to something in 2069.
We used to split things so 0-69 were 21st century, and 70-99 were 20th.
Change that (this requires a change in the parsedate ATF tests which
test this specific boundary).
While here, add support for another POSIX requirement, that the radix
char before fractional seconds can be either a ',' or a '.'. We used
to allow only '.', add support for ','. This is something of a meaningless
change, as parsedate() returns a time_t in which there is no way to
represent fractional seconds, so there's little point in ever specifying
them regardless of what char is used for the "decimal point" - they will
be ignored anyway. But at least fractional seconds using a ',' as the
radix char will no longer cause the conversion to fail (or do something else
bizarre).
