Обсуждение: Timestamps in Views

Hi,
I  use a data formatting in views  (to_char(last_update, 'YYYY-MM-DD
HH:MM:SS') as last_update and noticed that the last update returned is
the creation date of the view or not the actual value of the
last_update.(last _update is a timestamp).

What do I need to do to display the actuall value?

Thanks
Alex

It doesn't sound likely - could you provide the view definition and a couple
of lines of output?

Richard,
have a look I also don't quite understand why it is happening.
The dates returned are actually not the creation date of the view but just a different date.
Thanks
Alex

Ah! got it - you're using MM for month and minute. It'll be "m" or "i" or
something.

I've done the same, and looked at the code 100 times without noticing it.
