  That's a little unusual, and therefore a bit more difficult.

  There are a few things going on here.  What do you want to do *during* that time?  i.e. what happens if the user logs in between 0200-0600?

  If there's outside of that time, it's a bit simpler.  Just calculate how far away 0200 is, and then add 0-(4*3600) random seconds.

  Exactly how to do this isn't trivial.  TBH, the simplest solution might be a short Perl or Python script.  The "unlang" language isn't really intended to be a general purpose programming language.
