Hi Neall, You wrote to GORD HANNAH on 07.03.03 about "SET TZ= ???": NM>> What will I put on the SET TZ= NM>> command? GH>> Try this:SET TZ=PHT-8PHT,1,1,1,0,1,1,1,0,0 NM> I am curious about those strings, I will appreciate it if you can NM> explain those string of commands to me. ;) Make sure that your message reader screen is set to at least 80 columns wide for this Neall. I quote from one of the "bibles" :- ======================== Quote on =============================== VisualAge C++ TZ setting ======================== Example (for Germany): SET TZ=CET-1CST,3,-1,0,7200,10,-1,0,10800,3600 3 = starting month (1..12): march -1 = starting week (-4..4): last week of this month 0 = starting day: sunday 7200 = starting time (seconds): 02:00:00 10 = ending month: october -1 = ending week: last week of this month 0 = ending day sunday 10800 = ending time (seconds): 03:00:00 3600 = amount of time change (s): 01:00:00 This variable is used to describe the timezone information that the locale will use. To set TZ, use the SET which has the following format: ﾚﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄｿｳｳｳ >>ﾄﾄSETﾄﾄTZﾄﾄ=ﾄﾄSSSﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄ> ｳｳﾀﾄﾂﾄﾄﾄﾂﾄﾄhﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾙｳｳﾃﾄ+ﾄｴﾀﾄ:ﾄﾄmﾄﾄﾂﾄﾄﾄﾄﾄﾄﾂﾄﾙｳｳﾀﾄﾁﾄﾙﾀﾄ:ﾄﾄsﾄﾙｳｳｳｳ >ﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄ>< ｳｳﾀﾄDDDﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾙｳｳﾀﾄ,sm,sw,sd,st,em,ew,ed,et,shiftﾄﾙｳｳｳﾀﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾙ The values for the TZ variable are defined below.

It does not set any values for the start and end date of daylight saving time or the time shifted. When TZ is not present, the default is EST5EDT, the "C" locale value. When only the standard time zone is specified, the default value of n (difference in hours from GMT) is 0 instead of 5. If you give values for any of sm, sw, sd, st, em, ew, ed, et, or shift, you must give values for all of them or the entire statement is considered not valid, and the time zone information is not changed. The value of TZ can be accessed and changed by the tzset function. For more information on tzset, see the C Library Reference.
