Hi there,<br>
<br>
I am Mok Ly Yng. I found my name mentioned in the latest version of
the tz data file. I have added a few other points to the Malaysia
and Singapore time zone info. These are marked in
<font color="#0000FF">blue</font>.<br>
<br>
For both Malaysia and Singapore, for many years in the past versions of
this file, the first date was listed as 'Until 1880'. This was the
date which prompted my research into the history of legal time in
Singapore and Malaysia. It turned out that '1880' was the founding
year of Kuala Lumpur. So, it could not have been an 'Until'
date.<br>
<br>
Kuala Lumpur kept its own Local Mean Time of 6:46:46 until it was changed
to Singapore's Mean Time on 01 Jan 1901, along with the rest of the other
Malay States under British rule. The difference of 2 sec between
6:46:46 and 6:46:48 (as in the original version) was probably due to the
rounding off of arc seconds in the longitude value.<br>
<br>
Singapore was founded in 1819 and had kept different local mean times
depending on the different longitude values as determined by different
authorities over the years.<br>
<br>
The only uncertainty remaining is the WWII years of 1942-1945. I am
still trying to find out the exact dates of time changes.<br>
<br>
Regards,<br>
<br>
Mok<br>
