"microprocessor" isn't a well defined term.

If you have an OS, use the time conversion package.  They all use the same 
collection of zone info files.

If you don't have an OS, use a system with an OS to pre-compute the 
switch-dates for the next N years and store them in a table.  You will have to 
update that table whenever Congress screws with things.

These are my opinions.  I hate spam.
