   i didn't say anyting about a BBS ;)   
      
    MK> Do you have or know of a working example that indeed gets it right?   
      
   i've known of several over the years... i think Synchronet BBS does but i   
   haven't looked very closely to see for sure... i'm not positive but maybe some   
   of the sysop readers like golded and timed... i know i've seen the capability   
   in the past because it was interesting to read a message that had only been   
   posted minutes before and i was able to tell this because the "date written"   
   displayed in the reader i was using was my local time and the writer was   
   several timezones removed... looking at the raw message showed the actual date   
   stored in the message...

   we're not tampering with anything... we taking one set of time representation   
   numbers and adjusting them to local or UTC time... it is a simple thing to do   
   if all the necessary parts are available...   
      
    MK> If I cared, for local display I would do something like this (using   
    MK> the datetime and TZUTC from "MSGID: 1:3634/12.73 5c3e3137");   
      
   yes, i'm very familiar with the date command... i normally use it for   
   something like this...   
      
     blahblah | tee $(date +%Y%m%d%H%M%SUTC%z)-blahblah.log   
      
   depending on the processing being logged, "%S" may be left out... and then   
   there's a majikal   
      
     $(date +%j)   
      
   that one might find useful when dealing with FTN nodelists and similar other   
   things that need the DOY for their work ;)
