Timecnt is three because there are three jumps in wall clock time recorded for Venezuela: one in 1912 (when it switches from Caracas Mean Time to time that's 4.5 hours different from UCT), one in 1965 (when it switches to 4.0 hours different), and one in 2007 (when it switches back to 4.5 hours different). --ado -----Original Message----- From: Mark Jennings [mailto:mark.1.jennings@vertu.com] Sent: Wednesday, April 22, 2009 12:16 To: tz@lecserver.nci.nih.gov Subject: America/Caracas Hi, # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Caracas -4:27:44 - LMT 1890 -4:27:40 - CMT 1912 Feb 12 # Caracas Mean Time? -4:30 - VET 1965 # Venezuela Time -4:00 - VET 2007 Dec 9 03:00 -4:30 - VET This is what I get when encoding with zic, 0000000 5a54 6669 0000 0000 0000 0000 0000 0000 0000010 0000 0000 0000 0300 0000 0300 0000 1800 0000020 0000 0300 0000 0300 0000 0800 1e93 3c2c <- timecnt, typecnt, charcnt 0000030 98f6 48ec 5b47 8792 0201 ff01 c1ff 0044 0000040 ff00 c0ff 00b8 ff04 c7ff 00c0 4304 544d 0000050 5600 5445 0400 58b2 0000 0000 0501 eca4 0000060 0001 0000 0702 1f86 0082 0000 0903 5367 0000070 0003 0000 0b04 8648 0084 0000 0d05 0b2b 0000080 0085 0000 0f06 3f0c 0006 0000 1007 72ed 0000090 0087 0000 1208 a6ce 0008 0000 1509 ca9f 00000a0 0089 0000 170a fe80 000a 0000 190b 3162 00000b0 008b 0000 1d0c ea25 000c 0000 210d e5da 00000c0 000d 0000 250e 9d9e 008e 0000 270f d17f 00000d0 000f 0000 2a10 f550 0090 0000 2c11 2932 00000e0 0011 0000 2e12 5c13 0092 0000 3013 24e7 00000f0 0013 0000 3314 48b8 0094 0000 3615 108c 0000100 0015 0000 4316 1bb7 0096 0000 4917 075c 0000110 0097 0000 0018 0000 0000 0000 Why is timecnt 3 ? I have written my own parser, but because timecnt = 3, it is not recognising that the offset should be -4:30. Many thanks Mark
