Guys,
I guess I'm the newest SQLite person on this email list and I

SQL Server has a function called datediff for date arithmetic. It
accepts three parameters. The first indicates the unit of scale
Not really that goofy, just very specific.
The SQL Server manual describes it this way:
Returns the number of date and time boundaries crossed between two
specified dates.

well, this is one second rounded up to the next full month...If that
is the kind of information you want
. It computes the number of date measurement
interval transitions that occur between the two dates.

I have been staring at this until I'm getting goofy.
