I was looking at some book of system programming.It mentioned to use a variable TZ with a colon : separate list which is used from /usr/share/zoneinfo probably the book is a bit outdated.I checked on my Ubuntu system
/usr/share/zoneinfo/Asia$ file Oral
gives following output
Oral: timezone data, version 2, 14 gmt time flags, 14 std time flags, no leap seconds, 51 transition times, 14 abbreviation chars
I tried opening it in vi but the text could not be read.
I also tried reading
/etc/localtime but here also it could not be read.
1) How can I basically read above type of files
2) Where is TZ environment variable defined in Ubuntu 10.04
