   exactly... the numeric string representation must be converted to a number for   
   the math... the tools you are using are doing that behind the scenes :shrug:   
      
    MK>   date --date="10 Mar 19  10:25:00 -0400" +%s = 1552227900

   one ""problem"" here is that you are using RFC-oriented tools... they do not   
   work like FTN tools do so you are forced to either 1) convert their output as   
   needed or 2) complain about one side or the other not being ""done   
   properly""...

   your horizon is rather limited, though... anyone reading your posts for any   
   real length of time can see that...   
      
    MK> If you know different I'd appreciate hearing about it but from   
    MK> everything I have seen thus far the TZUTC does absoultely nothing and   
      
   i've used TZUTC specifically to display times in the local-to-the-bbs   
   timezone... there have been comments about how can a message be written in the   
   future but when it is pointed out that the message originated in Oz and is 12   
   or so hours ahead of new york, then it makes sense... not all systems do this   
   and there may very well be no indication that timezone conversion is even   
   being done... if the software you use and have seen hasn't made use of TZUTC,   
   that's an implementation problem... or not if they don't care to use it and   
   simply display the time stamps as given...   
      
    MK> is wrong given the lack of the + character where applicable.   
      
   again, you are stuck in non-FTN mode...

   Do you manage your own servers? If you are not running an IDS/IPS yer doin' it
