   Well, it's fairly simple. There's a modem line somewhere that
will do this. I have a SALT script that will do this (SALT is a 
C-like script language for the Telix terminal program), but it's
at home with my PC. I'll try to remember to post it tonight, along
with any docs I may find.
   I'm not familiar with the ins and outs of dialing out under
program control under Unix, so someone else will have to port it ...
all the modem has to do is
  1. call somewhere
  2. get a few lines of ASCII
  3. mark precisely what the time was when you got the info
  4. decode the info into a time stamp
  5. set the clock
  6. hang up after step 2 =8)
