Nope, but this will help you calculate the Julian Date Number, which
you'll need:
put the date into tDate
convert tDate from date to dateItems
if ((item 2 of tDate = 1) or (item 2 of tDate = 2)) then
put 1 into tDay
else
put 0 into tDay
end if
put item 1 of tDate + 4800 - tDay into tYear
put item 2 of tDate + (12 * tDay) - 3 into tMonth
put item 3 of tDate + \
((153 * tMonth + 2) div 5) + \
(365 * tYear) + \
(tYear div 4) - \
(tYear div 100) + \
(tYear div 400) - \
32045 into tJDN
