You could do something like:

   GridUtil.getDateTimeList(grid).get(0)

> day = (int)(dateTime.formattedString("dd", tz))

You could do:

julian = (int) (dateTime.formattedString("DDD", tz)

> # julian Day
> feb=28
> if ((((year % 4) == 0) and not((year % 100) == 0)) or ((year % 400) == 0)):
> feb = 29
> months = [31,feb,31,30,31,30,31,31,30,31,30,31]
> monthdays = 0
> for i in range(0,month-1):
> monthdays = monthdays + months[i]
> julianday = day + monthdays
> print "Julian Day:",julianday
