Calling these two functions within template?

[robertpro2a]

Hi,
I have a variable in my "results_bit" like this:

$row[column_2];

It's a unix timestamp, so I'd like to format it into a time/date. I know I can do it in Smarty so I imagine I can do it with VBulletin.

The other function I request is to get the username string from this variable:

$row[user_id];


Is this possible? Thanks!
