Problem Statement

Choose popular date libraries used by your language and show the   epoch   those libraries use. A demonstration is preferable   (e.g. setting the internal representation of the date to 0 ms/ns/etc.,   or another way that will still show the epoch even if it is changed behind the scenes by the implementers),   but text from (with links to) documentation is also acceptable where a demonstration is impossible/impractical. For consistency's sake, show the date in UTC time where possible.

Let's start with the solution:

window 1

print date$
print date$("d MMM yyyy")
print date$("EEE, MMM d, yyyy")
print date$("MMMM d, yyyy ")
print date$("MMMM d, yyyy G")
print "This is day ";date$("D");" of the year"
print
print time$
print time$("hh:mm:ss")
print time$("h:mm a")
print time$("h:mm a zzz")
print
print time$("h:mm a ZZZZ "); date$("MMMM d, yyyy G")
