Hi, Mauritius use daylight saving since 2008-11. The Olson database has been updated to reflect the Mauritius timezone change at the end of 2008 (maybe since tzdata-2008f or tzdata-2008g, not really sure).
Postgresql is supposed to have the correct Mauritius timezone since 8.3.5 (http://www.postgresql.org/docs/8.3/interactive/release-8-3-5.html). From a debian box configured in the Mauritius timezone : $ date Wed Mar 4 11:10:01 MUST 2009 $ psql -c "SELECT '2009-01-01 00:56:00 MUT'::timestamp" timestamp --------------------- 2009-01-01 00:56:00 (1 row) $ psql -c "SELECT '2009-01-01 00:56:00 MUST'::timestamp" ERROR: invalid input syntax for type timestamp: "2009-01-01 00:56:00 MUST" As you can see Posgresql does not recognize the "MUST" (Mauritius Summer Time). For reference, here is the content of the tzdata file related to Mauritius : # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Mauritius 1982 only - Oct 10 0:00 1:00 S Rule Mauritius 1983 only - Mar 21 0:00 0 - Rule Mauritius 2008 max - Oct lastSun 2:00s 1:00 S Rule Mauritius 2009 max - Mar lastSun 2:00s 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Indian/Mauritius 3:50:00 - LMT 1907 # Port Louis 4:00 Mauritius MU%sT # Mauritius Time Is this a bug in Posgresql or am I missing something ? This problem was encountered with Postgresql 8.3.5 and 8.3.6.
