Bug in KCJewishCalendar.m -workingDateAdjustedForSunset implementation

[Benny-iPhone]

Code is:
BOOL isAfterSunset = [[self sunset] timeIntervalSinceNow] < 0;

Which might be correct when testing current time. But when check for future/past time (or running a unit-test) this can lead to an error.
I think it's better to compare to workingDate like the next implementation:

BOOL isAfterSunset = (self.workingDate.timeIntervalSince1970 - [self sunset].timeIntervalSince1970) > 0;
