Hi,
I have a program using tzset() and then reading tzname[0] and tzname[1] to
detect my local timezone, my testing shows it returns wrong value on Ubuntu
karmic as well as Fedora 11.
The samle code is as below:
tzset()
printf ("tzname[0] %s\n", tzname[0]);
printf ("tzname[1] %s\n", tzname[1]);
---
Here are the output on Ubuntu karmic:
TZ=':Asia/Shanghai' ./test
tzname 0 CST
tzname 1 CDT
TZ=':America/Chicago' ./test
tzname 0 CST
tzname 1 CDT
TZ=':Asia/Tokyo' ./test
tzname 0 JST
tzname 1 JDT
What I found is it goes wrong for Asia/Shanghai timezone, the std
field(tzname[0] is ambiguous and the dst field should be empty
since China don't use Daylight saving.
