relative time fn (RelativeTimeFn)
A means of converting TimePositions
between different TimeZones. (RelativeTimeFn time zone)
denotes the TimePosition in CoordinatedUniversalTime that is
contemporaneous with the TimePosition time in TimeZone zone.
For example, (RelativeTimeFn (MeasureFn 14 Hour) EasternTimeZone)
would return the value (MeasureFn 19 Hour).
