Function std.datetime.DateTime.julianDay
The Julian day
for this
DateTime
at the given time. For example, prior to noon,
1996-03-31 would be the Julian day
number 2_450_173, so this function
returns 2_450_173, while from noon onward, the julian day
number would
be 2_450_174, so this function returns 2_450_174.
