Examples

toTz(Sys.time(), "America/New_York", "Europe/London")
# this redoes the 'Armstrong on the moon in NYC and Sydney' example
# note that the default print method will print the return object in _your local time_
toTz(ISOdatetime(1969,7,20,22,56,0,tz="UTC"), "America/New_York", "Australia/Sydney", verbose=TRUE)
# whereas explicitly formating for Sydney time does the right thing
format(toTz(ISOdatetime(1969,7,20,22,56,0,tz="UTC"), 
            "America/New_York", "Australia/Sydney", verbose=TRUE), 
       tz="Australia/Sydney")
