`time' cannot be as simple as you seem to think.  For starters, it needs 
to support the different time zones, so it needs at least to look at the 
environment variable TZ.  DJGPP's version does much more than that, and 
uses a disk-based database for all the different timezone rules.

Perhaps you should look at the sources of `time' to appreciate how 
complicated it is.
