Shell Programming and Scripting

hi friends,
this is my first time with this type of script so please pardon my ignorance. i have this script in which a piece of code needs to be added which can have the Asia/Hong kong time as well. system date and format is GMT so no problem with GMT and even EST is covered..i have ato add new File watchers and that requires an update to the following script to support Asia time as well.


#!/bin/sh

any help would be much appreciated..

IF you on a POSIX compliant system you can use the TZ variable. This machine is CST.
It doesn't have a TZTAB entry (HPUX thing for timezones) for Hong Kong but it doesn't matter. I am assuming HK is UTC+8:

Code:

csadev:/home/jmcnama> date +%c
Wed Mar 19 11:49:58 2008
csadev:/home/jmcnama> echo $TZ
CST6CDT
csadev:/home/jmcnama> TZ=HST-8HST
csadev:/home/jmcnama> date +%c
Thu Mar 20 00:51:52 2008

i dont want to change the server time...i wanted to add some script to mine so if i use this file it will support Asia time also..server time should stay as it is (GMT)...any thoughts!!!!!

TZ is a per process thing, set it back to EST5EDT or whatever when you are done in the script. This DOES NOT AFFECT SYSTEM TIME.

Code:

hong_kong()
{
   TZ=HST-8HST
   date "+%c"
   TZ=CST6CDT
}

if I have to change it form GMT would it still be "TZ=HST-8HST" or "TZ=HST-7HST" since the day light time came into effect?
Otherwise it works...Really eally appreciate it...... ) and ur rite it doesnt effect system time...

you didn't specify which OS your using, so you'd want to doublecheck what
the timezone entry is for Hongkong, just to be safe.
Solaris is TZ=Hongkong

if I have to change it form GMT would it still be "TZ=HST-8HST" or "TZ=HST-7HST" since the day light time came into effect?

No, the system will know how to compensate for EST or DST with the default entry.

PS: Hongknog does not use day light saving time!
