Oh I hadn't even thought about multiplying an interval, that's a very
clean approach. Prior to e-mailing the list I'd tried something similar
to (but not as thorough as) Adrian's suggestion and it had failed, but
if it works I like the look of this.
I vaguely recall having a similar interval manipulation headache in a
PHP portion of this project, I shall try the same thing there.
Thank you so much!
