the best, easiest and safest way to do this is to use libc's date
manipulation functions such as gmtime() and localtime(). You can
increase/decrease on absolute basis using mktime() to convert to
seconds, then operate in seconds, and then convert back to the
break-down format to display.
By the way, we should have these functions in embryo, so our clock
could handle timezones feed to gadgets using offsets from gmt :-)
