Reserving D in %s for 1:00 offset as has been done over years, i.e. is established practice
I'm not quite following all the proposal in this area, but "D" also stands for "Double", as in BDST for British Double Summer Time. There is a similar usage of "H" for Half, as in CKHST for Cook Islands Half Summer Time. If memory serves, CKHST, UYHST, etc. are my own invention, while BDST is not: it comes from contemporaneous British sources. I came up with HST by analogy from DST.
My statement was a shortening, that shortening made it wrong.
I meant in the position immediately before the last T.
For saving time there is immediately before the last T D 1:00 S 1:00 DD 2:00 DS 2:00 HD 0:30 HS 0:30 and 0:20
Conforming with this established practice is LHHDT for Lord Howe Half Daylight saving Time.
Why are you encoding meaning in abbreviations? Abbreviations are a disply-only feature. Also, there is no such thing as "Half Daylight Saving Time". It's an on/off switch, no matter whether they change by 30 minutes or 427 seconds. cheers, Derick
