Hi, The latest version of the timezone data file ftp://elsie.nci.nih.gov/pub/tzdata2006c.tar.gz contains the updated time offset for Sri Lanka, but the text field is set to IST. I think this needs to be corrected to LKT. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Colombo 5:19:24 - LMT 1880 5:19:32 - MMT 1906 # Moratuwa Mean Time 5:30 - IST 1942 Jan 5 5:30 0:30 IHST 1942 Sep 5:30 1:00 IST 1945 Oct 16 2:00 5:30 - IST 1996 May 25 0:00 6:30 - LKT 1996 Oct 26 0:30 6:00 - LKT 2006 Apr 14 5:30 - IST Thanks.
