I am trying to find out the time on different timezone by using the TZ variable.

However, the timezone using the country code is differnet from using the GMT code.

For example:
for HK ,GMT+8
for Japan, GMT+9
for Aus ,GMT+10

so i write the follow script to test on it.
# cat check.sh
d=`TZ=$* date`
echo "Today is `date` ; $* = `echo $d`"#

try some output on below:
Today is Sun Aug 6 06:07:29 HKT 2006 ; Hongkong = Sun Aug 6 06:07:29 HKT 2006
Today is Sun Aug 6 06:07:29 HKT 2006 ; GMT+8 = Sat Aug 5 14:07:29 GMT 2006
Today is Sun Aug 6 06:07:29 HKT 2006 ; Japan = Sun Aug 6 07:07:29 JST 2006
Today is Sun Aug 6 06:07:29 HKT 2006 ; GMT+9 = Sat Aug 5 13:07:29 GMT 2006
Today is Sun Aug 6 06:07:29 HKT 2006 ; Australia/NSW = Sun Aug 6 08:07:29 EST 2006
Today is Sun Aug 6 06:07:29 HKT 2006 ; GMT+10 = Sat Aug 5 12:07:29 GMT 2006

Using the GMT will get a wrong result of time.
Does anyone know what wrong on setting this TZ ?


Thanks

I think you need to use "GMT-8" instead of "GMT+8", here is the sample:

admin@sco1:/home/admin$export TZ=GMT
admin@sco1:/home/admin$date
Mon Aug 14 16:32:36 GMT 2006
admin@sco1:/home/admin$export TZ=GMT-8
admin@sco1:/home/admin$date
Tue Aug 15 00:32:49 GMT 2006
admin@sco1:/home/admin$export TZ=GMT+8
admin@sco1:/home/admin$date
Mon Aug 14 08:34:50 GMT 2006
