  Modified Files:  
   docs/v322_new.md src/sbbs3/xtrn_sec.cpp  
  Log Message:  
  Populate CHAIN.TXT lines 24 and 25 (call time and time used)  
    
  These two WWIV drop-file fields have been hard-coded to 0 since the  
  initial v3.00c check-in (7e3e47141a, 2000-10-10). Line 24 is the time  
  of the call expressed as seconds past midnight; line 25 is the number  
  of seconds the user has been on the system so far, so doors that show  
  "time on" -- or recover the current time from the pair -- saw zeros.  
    
  Line 25 uses timeon() rather than a raw now-starttime subtraction: it  
  measures against the same logon timestamp line 24 is derived from, so  
  the two stay consistent, and it clamps a negative result instead of  
  printing it through an unsigned conversion.
