D'Arcy...
> Have you considered this?
I considered integrating the begin and end times into the table. I'm
capturing the data via ACPI events, so it's "transactional" by nature.
I want to be able to keep track of false transitions (hence the
is_outage field).
I'm looking for a way to simplify the transitions output on my web
browser, and I want to combine an offline and a corresponding online
time into a single line.

It's nothing complex at all. The power in my neighborhood is
infamously unstable, and I'm merely keep records to complain as much
as I can to the power company.
Thanks for taking the time to reply!
