Time zone offsets vary by date, and this helper function converts a Datetime object from one given timezone to another.

Examples

if (FALSE) {
toTz(Sys.time(), "America/New_York", "Europe/London")
# this redoes the 'Armstrong on the moon in NYC and Sydney' example
toTz(ISOdatetime(1969,7,20,22,56,0,tz="UTC"), "America/New_York", "Australia/Sydney", verbose=TRUE)
# we can also explicitly format for Sydney time 
format(toTz(ISOdatetime(1969,7,20,22,56,0,tz="UTC"), 
            "America/New_York", "Australia/Sydney", verbose=TRUE), 
       tz="Australia/Sydney")
