[CLUE-Tech] databases and timestamps ... 'since' idiom

[Dave Price]

could someone here please point me in the direction of a simple way to 
implement a 'since'
syntax, either in bash or sql (or other) ...

what i have in mind is a comparison of timestamps contained in both 
flat-file and postgres table to see if they are 'since' a given time ... 
i.e. between 'then' and 'now()'

is there a nice shorthand or 'idiom' for this expression?

aloha,
