Hi All,

My goal is to provide a user interface showing the information derived from the TZ zone name. Based on the selected TZ zone name by the user, I will assign the corresponding POSIX time zone string to the Linux /tmp/TZ file. This way the local time will show up properly for the user.

However, I am having difficulty to find a reliable source for POSIX time zone string representation for each defined time zone in the Olson database. Also, the Olson database is changing many times a year which is making it difficult to hardcode anything in advance.

I am sure that my problem already encountered by someone on this mailing list and I am wandering if there is a way to query the current version of the Olson database with some tool to return the related POSIX representation for the requested time zone.

I don’t know if there is an alternative way, but I am also wandering if the TZ time zone name can used directly without going through the POSIX representation of the time zone.

Note: POSIX time zone representation for me is the following. The TZ zone name America/Los_angeles is represented as PST8PDT,M3.2.0,M11.1.0.
