ah!  yes, the code is complete but the instructions are not.

Yes, Google do not appear to be very forthcoming with their parsing
algorithms.  I had to do a lot of trial and error, especially to
support block entries, and I think the result is fragile at best.

I this moment (swamped with a project application), all I can suggest
is you look at org's time parsing codes for handling new agenda
entries.  The text must be parsed somewhere...  If you use the same
code within the advice, you should be able to pick off the times.

I'll add this to my todo list but I won't get a chance to play anytime
soon unfortunately.

Maybe post what you did to this list and somebody might be able to
help?

Can the diary file not be your all-in-one org file?
