My bad; yes it is an offset. So you would need to tell it to add
it to the 'beginning of unix time' which is 1/1/1970 GMT, which is
10:00am 1/1/1970 Sydney time:
$ date
Thu Nov 25 13:00:08 EST 2004
$ date +%s
1101348011
$ date --date '1/1/1970 10:00am + 1101348011 seconds'
Thu Nov 25 13:00:11 EST 2004
The syntax --date thing is fun -- you can use words like 'yesterday'
and 'now' but fairly underspecified and you can get surprised :
e.g. adding 2 assumes hours and adds to the _beginning_ of the date
but adding 2 seconds adds to the _current_ time.
$ date --date 'now + 2'
Thu Nov 25 02:00:00 EST 2004
$ date --date 'now + 2 seconds'
Thu Nov 25 13:03:48 EST 2004
Hmmmm.
