Hi, Can someone enlighten me? I know that I can insert date/time data along with time zone info into the timestamp with time zone data type. My question is, can I extract the *original* time zone info afterward? I seems impossible. May be I should use date + time with time zone to preserve the time zone info? It seems the time with time zone data type can do this. test=# create table t2(t time with time zone); CREATE TABLE test=# test=# insert into t2 values('12:34:56 +0400'); INSERT 0 1 test=# select * from t2; t ------------- 12:34:56+04 (1 row) test=# select t at time zone 'jst' from t2; timezone ------------- 17:34:56+09 (1 row) test=# select t::time from t2; t ---------- 12:34:56 (1 row) -- Tatsuo Ishii SRA OSS, Inc.
