Question

I need to subtract time/day using a mysql query;

It is something like 02:00 in (GMT-1) on saturday – wednesday 00:59 in (GMT+5)

How can I do this with a sql query? and get result like 3 days 7 hours and 1 minutes

edit: both days are of same week

Answer 1

Assuming the dates for this work, and thanks to @symcbean I could get it to work with TIMEDIFF

SELECT TIMEDIFF(CONVERT_TZ('2012-04-15 02:00:00', '-01:00', '+05:00'), '2012-04-12 00:59:00');

and for the days hours and minutes:

SELECT CONCAT(
    FLOOR(HOUR(TIMEDIFF(CONVERT_TZ('2012-04-15 02:00:00', '-01:00', '+05:00'), '2012-04-12 00:59:00')) / 24), ' days ',
    MOD(HOUR(TIMEDIFF(CONVERT_TZ('2012-04-15 02:00:00', '-01:00', '+05:00'), '2012-04-12 00:59:00')), 24), ' hours ',
    MINUTE(TIMEDIFF(CONVERT_TZ('2012-04-15 02:00:00', '-01:00', '+05:00'), '2012-04-12 00:59:00')), ' minutes') as TIMEDIFF;
