Simple Date Time support for Julia. EXPERIMENTAL

Dates and Times for Julia

The types and functions in this class store and manipulate representations of dates and times Instances are stored internally as a Julian Date (jd), which is a representation of dates counting linearly in days since midnight localtime on January 1, 4713 BCE. The original Julian Day Number, counting in days since noon GMT, is refered to as the astronomical julian date (ajd) within this code base.

Only minimal timezone support currently exists. DateTime objects keep track of timezones supplied, and use timezones  in difference calculations. However, no timezone conversion functionality is provided. DST is also not considered by this code. Both these items are cosidered to be the responsibility of the calling code.

##Examples

load("SimpleDate/src/SimpleDate")
using SimpleDate

d = datetime(2012, 4, 24, 13,10,5) 
@assert hour(d) == 13
@assert minute(d)==10
@assert second(d) == 5
@assert mday(d) == 24
@assert month(d) == 4
@assert year(d) == 2012

d = date(2012,2,1)
@assert year(d) == 2012
@assert month(d) == 2
@assert mday(d) == 1
@assert wday(d) == 4 #Wednesday
