CAP_WAKE_ALARM could readily be CAP_TIME.

Actually, I don't quite understand what you mean with that sentence.
Could you elaborate?

Should have said CAP_SYS_TIME

Setting an alarm could be considered a time management function,
depending on what it actually does.

Just a nit here. CAP_WAKE_ALARM is more about the privilege of waking
a system from suspend, while CAP_SYS_TIME covers the ability to set
the time. One wouldn't necessarily want to give applications which
could wake a system up the capability to also set the time.

Doesn't really matter, except that an ignorant developer
might make the mistake I did and assume that WAKE_ALARM
was somehow related to time management. If you want to use
it as an example don't let my dunderheadedness get in your
way.

Again, thank you for taking this on. It should be a
big help.
