I want to create a compiled TZ database file from a posix expression.
Is there any unix utility which can create the TZ database out of the posix expression?
I do check the zic command but I was not able to find a way to provide posix expression rules as input to the zic. Is there any way to use posix expression with zic? eg. EST5EDT,M10.3.0,M2.3.0
I need the compiled database as I want timezone to be persistent across all the sessions so that /etc/localtime can be linked to the compiled database.
Directly setting TZ variable to posix expression will not help as it will not be persistent over session as well after reboot.
