Yet another master into zoom buffer branch merge (with formatting all done!)

Does What It Says On The Tin (DWISOTT).

@matthieu fixed up the test. At the size of the time values I see +1 shouldn't be representable, so to me the mystery is why it worked in the first place. Maybe the absolute size of time has increased!

Never had issues with any other compiler before. But the fix makes sense! No idea why it ever worked.

added zooms label
