Yes, and no.
Yes, you can access (a certain form of) the Sybase date handling
routines from perl, but this only available in the Sybase::CTlib module
(requires perl5.001m or better).
The available calls are:
@arr = $date->crack; # Calls cs_dt_crack().
$date2 = $date1->calc($days, $msecs); # add/substractdays and
milliseconds to $date1.
($date, $msecs) = $date1->diff($date2); # number of days/millisecs
between date1 and date2.
You can also convert a Sybase date (which has a base value of January 1
1900) to a Unix time_t value using one of $date->mktime,
