Scott,

I'd found those APIs, but you saved me the time of coding the procedure,
thanks muchly!

There's an API which will do MOST (but not all) of the work for you.
Specifically, it does not know how to format an offset from UTC (the
"-0500" part)

The API that does all of the formatting is the "CEEDATM" API which can
be found in the "ILE CEE APIs" manual.

Here's an example of what you're trying to do:

      ** Get local time API
     D CEELOCT         PR                  opdesc
     D   output_lil                  10U 0
     D   output_secs                  8F
     D   output_greg                 17A

      ** Convert to arbitrary timestamp API
     D CEEDATM         PR                  opdesc
     D   input_secs                   8F
     D   picture                     32A   const
     D   output                      32A

      * Get offset from UTC API
     D CEEUTCO         PR
     D  hours                        10I 0
     D  minutes                      10I 0
     D  seconds                       8F

     D discard1        S             10U 0
     D cur_time        S              8F
     D discard2        S             17A
     D mail_date       S             32A
     D hrs2utc         s             10I 0
     D mins2utc        s             10I 0
     D discard3        s              8F
     D hh              s              2A
     D mm              s              2A

     C* Get current local time from clock:
     c                   callp     CEELOCT(discard1: cur_time: discard2)

     C* Convert to e-mail format:
     c                   callp     CEEDATM(cur_time:
     c                              'Www, DD Mmm YYYY HH:MI:SS':
     c                              mail_date)

     C* Retrieve offset from UTC
     c                   callp     CEEUTCO(hrs2utc: mins2utc: discard3)

     C* Format the UTC offset nicely
     C*   and tack it onto the string...
     c                   if        hrs2utc < 0
     c                   eval      mail_date = %trimr(mail_date) + ' -'
     c                   eval      hrs2utc = 0 - hrs2utc
     c                   else
     c                   eval      mail_date = %trimr(mail_date) + ' +'
     c                   endif

     c                   move      hrs2utc       hh
     c                   move      mins2utc      mm
     c                   eval      mail_date = %trimr(mail_date) + hh + mm

     C* Let's see if that worked :)
     c                   dsply                   mail_date

     c                   eval      *inlr = *on
