I got bitten because in the UK (where one would expect 1970-01-01 00:00 to be UTC 0) some politicians decided to mess around with daylight savings time from 1968 to 1971; it was permanently BST (+0100). That means that on my computer the following is true: $ date --date="1970-01-01 00:00" +"%F %T %z (%Z)" 1970-01-01 00:00:00 +0100 (BST) This of course means that the --date argument to date is specified in local time, not UTC. So when the hooks--update script does this: date=$(date --date="1970-01-01 00:00:00 $ts seconds") It's actually saying (in my timezone) "1970-01-01 01:00:00 UTC" + $ts. Clearly this is wrong. The UNIX epoch started at midnight UTC not 1am UTC. This leads to the tagged time in hooks--update being shown as one hour earlier than the true tagged time (in my timezone). The problem would be worse for other timezones. For a +1300 timezone on 1970-01-01, the tagged time would be 13 hours earlier. Oops. The solution is to force the reference time to UTC, which is what this patch does. In my timezone: $ date --date="1970-01-01 00:00 +0000" +"%F %T %z (%Z)" 1970-01-01 01:00:00 +0100 (BST) Much better.
