I emailed the patch purely for easy review from those on the list. This is common practice in open-source programming projects. The source itself is not meant to be actually pulled out of the emails.

We are not inventing anything new just using what is commonly used in Australia, as far as I've seen there is no defined syntax used for abbreviations other than that which are trying to create. Rather abbreviations are meant to reflect what is used by the Country they are defined for.

 "Changes to existing entries SHALL reflect the consensus on the ground in the region covered by that entry."

Subject: [tz] Patch use LHDT/LHST/LHHDT since HD HS DD DS are common practice

Patch australasia.20130411.withLHHDT is linked from
http://anna.info/wiki/ANNA_time_zone_database - I don't link to the
actual location, because that may change. And I don't email, because I
don't know what the email client does with the file.

The patch includes
AEST/AEDT ACST/ACDT AWST/AWDT CWST/CWDT LHDT/LHST/LHHDT

--------
The bom.gov.au-patch introduces new syntax, which for itself might be
fine, but this new syntax is less informative than the established one
and might be seen as deterioration to the whole database.

No single use of single "D" for non-1:00 saving has been found by me.
There is one single "D" in a LHDT but there it referred to a 1:00
saving.

Be consistent, apply common practice established by the maintainers and use:

HD 0:30
LHHDT Australia/Lord_Howe

For non 1:00 DST offsets the database contains:

DD 2:00
NDDT America/St_Johns
IDDT Asia/Jerusalem

DS 2:00
MDST - Moscow Double Summer Time,
BDST - British Double Summer Time

HD 0:30
CHDT America/Belize CHDT
EHDT America/Santo_Domingo

HS 0:30
UYHST America/Montevideo
IHST Asia/Colombo
CKHST Pacific/Rarotonga

HS 0:20
GHST Africa/Accra
