If you can live with mean solar time, rather than sundial time, all 
modern Unix-like systems can do this once calibrated.  Although you 
might think in terms of of quarter hour timezones (Nepal is on a quarter 
hour), the Olson already has mean solar time defined for many places, 
for dates earlier than the introduction of global time standards 
(although there may be some limitations on using that information with 
times before the Posix epoch).

You can create your own solar timezones by compiling suitable tables for 
your own location.
