Well, this would be a technologically late POD, but the adoption of a time system based on Planck Time.
The habit of having the day start at midnight is indeed counterintuitive and relatively new. Traditionally, the Jewish day vbegind with night (dusk is when one day ends and logically, the next begins) while the roman one divides into a day half (starting at sunrise and coming first) and a night half (strating at sunset and coming next).
Of course, sunrise and sunset are moving targets, and that gives you lots of baggage when you want to be scientific.
As long as you're on earth, you'll have some constants. There is the year - noticeable even in the tropics - and the day, and the two don't really align, though you won't notice until you start counting over long periods of time. The moon's phases are also pretty unmisable. Between these three things, you have to create a system that more or less works. Everything else is up to you.
Because base 12 is much more awesome and useful than base 10.Also dividing the day into 24 hrs, hours into 60 min, and minutes into 60 seconds seems really arbitrary (I know there are reasons for this but It still makes no sense).
How bout a day of 10 hours, (each would be 2.4 or OTL's hours). These into sets of 10 "minutes" (although they are more like 15 minuets of OTL), and like that.

I've wondered if a civilization could come up with a civil calendar based on thirteen 28-day months, then have a one-or-two day civil holiday to keep more or less in line with the solar year.

The only way to make it work is by having two calendars (a solar and a lunar) and following both. The solar gives you days and years but really nothing in between, the lunar gives you the middle measurements. Whenever the line up it can mean a new century.
