Time difference changed in 7.2

Hi,

I have exactly the same problem but haven't seen a reply with a solution as
yet. Anybody got any ideas?

Thanks, Alfred Tuinman

Hi,

The difference between two times (interval) seems to have undergone a
change from 7.1 to 7.2. For example
'1:00'::time - '23:00'::time = @ 2 hours in 7.1 and,
'1:00'::time - '23:00'::time = @ 22 hours ago in 7.2.
I assume there must be some sound reason for this change, but I have
used time differences at loads of places in my considerably large
application and the whole thing goes (not surprisingly) completely
haywire.
Is there some way I can revert to the old behaviour? Downgrading my
postgres version is not a choice :). IAC, since
'23:00'::time + '1:00'::interval = '1:00'::time,
