Table based lookup is highly undesirable but will do if there are no
other solutions available. Does anyone know how this is done?
In astronomy...
Longitude to local time
GMT ± (Longitude/15) = local time
Given he said "given the social and political issues of time zone" I suspect astronomy is not his goal.
