My first suggestion would be to work with Unix times (that is, store
your time as "seconds since 1970", also called a time_t). That's
forced to be on UTC (but ignoring leap seconds) so you don't have to
worry about timezones or DST, and incrementing by X minutes is simply
adding X*60 to it. It makes your job a lot easier!
