All searches return nothing when I use time_t format (1970 epic date, expressed in seconds).

That's because the correct field name is 'ctime'.

Thanks! The field works, but the values seem a bit strange. At least half of my collection has the value as 0.

I'm using this as a possible method to find newly added songs.

The field was added in v2.0 (actually it was v1.1 at the time), so if you've got anything put on there with v1.0, it'll have a zero ctime. But, for your purposes, that's probably fine.

Thanks Roger. Now if I could just find a util to create ctime format so I could stop guestimating! ;-) Happen to have one?

Maybe I'll take a look at the query lexer and support VB-style date specifications or something...
