ordinal(y=-4712, d=1, h=0, min=0, s=0, of=0, sg=ITALY)public
The 24-hour clock is used. Negative values of h, min, and sec are treating as counting backwards from the end of the next larger unit (e.g. a min of -2 is treated as 58). No wraparound is performed. If an invalid time portion is specified, an ArgumentError is raised.
of is the offset from UTC as a fraction of a day (defaults to 0). sg specifies the Day of Calendar Reform.
y defaults to -4712, and d to 1; this is Julian Day Number day 0. The time values default to 0.
