(Fwd) Hi and some advice on Dates

G'day All,

I am pretty new to postgres and am using it as a backend for DB's
accessed via the web and Perl DBI. All this works really well and I
have a few db's up and running on our Intranet at work, where they're
quite heavily used.

My current project requires me to do some date calculations and I'm
stumped !

Could anyone help with the following: (I have not fixed data type yet,
I will be guided by any info I can get)

How to query a table and look for any records where
the value in a date field is greater than (say) 10 days ago

Calculate the difference between two times on the same day. (I have
experimented with age() and it sort of does wht I want..is there any
other way ?)

I've searched the archives without success and the doc's don't give
much away as far as this type of thing goes.

Thanks in anticipation.
Andrew
