Answer the receiver, since DateTime objects store themselves in Local time
Convert the receiver to UTC time, and answer a new DateTime object.
Answer the receiver’s offset from UTC to local time (e.g. +3600 seconds for Central Europe Time, -3600*6 seconds for Eastern Standard Time). The offset is expressed as a Duration
Answer a copy of the receiver with the offset from UTC to local time changed to anOffset (a Duration).
Answer an abbreviated indication of the receiver’s offset, expressed as ‘shhmm’, where ‘hh’ is the number of hours and ‘mm’ is the number of minutes between UTC and local time, and ‘s’ can be ‘+’ for the Eastern hemisphere and ‘-’ for the Western hemisphere.
Answer the time zone name for the receiver (currently, it is simply ‘GMT +xxxx’, where ‘xxxx’ is the receiver’s #timeZoneAbbreviation).
