Top Forums Shell Programming and Scripting How to configure time zone using POSIX format in Centos 5? Post 302746471 by DGPickett on Wednesday 19th of December 2012 12:15:22 PM

PERL has an embedded db that might help: cgi - Get time zone abbreviation using POSIX (Perl) - Stack Overflow

The Olson DB escribed: tz database - Wikipedia, the free encyclopedia

Noe GMT-14 is UTC + 14 hours is UTC - 10 hours is, according to the database:
List of tz database time zones - Wikipedia, the free encyclopedia
it is HST, so you would set TZ to HTC-10 or something like that. POSIX offset sign is backward of TZ: GMT/UTC standards reversed in timezone standards (and PHP, and wordpress, and Unix/Posix) | Stef's Blog

Of course, you might be off a day!
Code:
$ ( echo $TZ ; date ; TZ=GMT-14 ; date )
EST5EDT
Wed Dec 19 12:19:32 EST 2012
Thu Dec 20 07:19:32 GMT 2012
$ ( echo $TZ ; date ; TZ=GMT+14 ; date )
EST5EDT
Wed Dec 19 12:20:14 EST 2012
Wed Dec 19 03:20:14 GMT 2012
$ ( echo $TZ ; date ; TZ=GMT14 ; date )
EST5EDT
Wed Dec 19 12:21:18 EST 2012
Wed Dec 19 03:21:18 GMT 2012
$ ( echo $TZ ; date ; TZ=Pacific/Kiritimati ; date )
EST5EDT
Wed Dec 19 12:26:52 EST 2012
Wed Dec 19 17:26:52 Pacific/Kiritimati 2012
$ ( echo $TZ ; date ; TZ=Pacific/Kiritimati-14 ; date )
EST5EDT
Wed Dec 19 12:27:50 EST 2012
Thu Dec 20 07:27:50 Pacific/Kiritimati 2012
$

So, TZ sets the visible name, for which there should be a table of 3 place capital letter codes for every offset, but apparently there is not. Using more than 3 places may work some places.

BIND2CSV2(1)							 MaraDNS reference						      BIND2CSV2(1)

NAME
bind2csv2 - convert zone files from BIND to MaraDNS compatible format DESCRPTION
MaraDNS 1.3 has BIND zone file support. This means it is possible to use BIND zone files in MaraDNS. This makes it easier for people to use MaraDNS in mixed DNS server environments. Instead of having direct BIND zone file support, MaraDNS has a script, called bind2csv2, that converts BIND zone files in to the "csv2" zone file format that MaraDNS 1.2 and 1.3 use. The zone files generated by bind2csv2 are not MaraDNS 1.2 compatible; MaraDNS 1.3 is needed to read zone files generated by bind2csv2. bind2csv2 is a Python script, written in version 2.2.3 of the Python interpreter. The script should be compatible with more recent versions of Python. The script assumes Python is the file /usr/bin/python on your system; if Python is located elsewhere on your system, please change the first line of bind2csv2. Naturally, you will need the Python interpreter installed on your system to use bind2csv2. This is a well-known open source language supported by most modern Linux and BSD distributions. USAGE
To use the script, enter a directory containing BIND zone files, and invoke the script thusly: bind2csv2 -c zone1 zone2 zone3 Substitute "zone1", "zone2", and "zone3" with a list of one or more BIND zone files you wish be converted in to MaraDNS 1.3 csv2 zone files. Once the script is run, you should have files with names like "zone1.csv2", "zone2.csv2", and "zone3.csv2". These files are csv2 zone files that MaraDNS will be able to parse. Copy these csv2 zone files to a place where MaraDNS can find the zone files. Should there already be a "zone1.csv2" file when bind2csv2 is run, the "zone1.csv2" file will be replaced. OPTIONS
None. Bind2csv2 can only be used as above. BUGS
bind2csv2 is not a perfect zone file converter. In particular, bind2csv2 does not act like BIND when NS records have different TTLs. Please make sure all NS records in your BIND zone files have the same TTL. In addition, bind2csv2 also does not support all resource record types that BIND supports. Only the following RRs are supported by bind2csv2: A AAAA AFSDB CNAME GPOS HINFO ISDN LOC MB MD MF MG MINFO MR MX NS NSAP PTR PX RP RT SOA SPF SRV TXT WKS X25 MARADNS
