 ml> i now use the following based on info in the time868 help file...

 ml>   TZ=EST5EDT,3,2,0,7200,11,1,0,7200,3600

 MiL> For whatever reason my version I wrote to you earlier of this, 

 MiL>        TZ=CST5CDT,3,2,0,7200,11,1,0,7200,3600

 ml> according to the specs (and the TIME868 docs) this would be the
 ml> correct string...

it appears that i may have misinterpreted the TZ stuff that i've been
reading... in my ongoing attempts to get a working back system, i ran across
this in the gtak/gtar installation...

=====

Be sure you have a correct timezone setting in CONFIG.SYS. Else timestamps may
be incorrect when using archives from/on other systems, since the TAR archive
contains GMT timestamps.

The value of TZ has the following format (quoted from the EMX library
reference):

set TZ=TZ1[OFF,[TZ2[,SM,SW,SD,ST,EM,EW,ED,ET,SHIFT]]]

 TZ1  is the three-letter name of the standard timezone.

 OFF  is the offset to Coordinated Universal Time; positive values
      are to the west of the Prime Meridian, negative values are to
      the east of the Prime Meridian. The offset can be specified 
      as hours, hours and minutes, or hours, minutes, and seconds.
      Hours, minutes, and seconds are separated by colons. If OFF
      is not specified, an offset of 0 will be used (this may change
      in the future). 

 TZ2  is the three-letter name of the summer timezone (daylight 
      saving time). If TZ2 is not specified, daylight saving time 
      does not apply. If TZ2 is specified, daylight saving time 
      does apply; the remainder of the TZ's value specifies when and 
      how to change to and back from daylight saving time. SM 
      through ST define, in current local time, when to switch from
      standard time to daylight saving time, EM through ET define, 
      in current local time, when to switch from daylight saving 
      time to standard time (On the southern hemisphere, the end date 
      precedes the start date). SHIFT is the amount of change in 
      seconds. 

 SM   specifies the month (1 through 12) of the change. 

 SW   specifies the week of the change; if this value is zero, 

 SD   specifies the day of month (1 through 31). If SW is positive (1 
      through 4), the change occurs on weekday SD (0=Sunday through 
      6=Saturday) of the SWth week of the specified month. The first 
      week of a month starts on the first Sunday of the month. If SW 
      is negative (-1 through -4), the change occurs on weekday SD 
      (0=Sunday through 6=Saturday) of the -SWth week of the specified 
      month, counted from the end of the month (that is, -1 specifies 
      the last week of the month). The last week of a month starts on 
      the last Sunday of the month. ST specifies the time of the 
      change, in seconds. Note that ST is specified in local standard 
      time and ET is specified in local daylight saving time. 

Example: set TZ=CET-1CED,3,-1,0,7200,10,-1,0,10800,3600

In this example, the name of the standard time zone is CET, the name of the
summer time zone is CED. Daylight saving time starts at 2:00 on the last Sunday
of March and ends at 3:00 on the last Sunday of October. Time changes by one
hour in daylight savingtime.

If no characters follow TZ2, the rule `,4,1,0,3600,10,-1,0,7200,3600' will be
used: Daylight saving timestarts at 1:00 on the first Sunday of April and ends
at 2:00 on the last Sunday of October. Time changes by one hour in daylight
saving time.

===== end quote =====

it would appear that, by the last line, we are to use 1AM (3600) in the 7th
field as you've indicated with your change above... i guess this has to do with
using local non-saving time instead of simply using local time, whether in
saving time or not...

color me still confused...

PS: what's your callsign? i know you've posted it before but i haven't found
it... i've been working with a returning sysop who is also a HAM and it is
likely that you two have talked many times on the air as well as in fido and
may not have even known it... i'm wanting to give him your callsign as he
likely knows you by that more than by your name ;)
