I was under the impression that the {Qoylu’pu’} method of time used a 12-hour clock instead of a 24-hour clock. {wa’maH loSvatlh rep = cha’logh Qoylu’pu’}

Am I wrong about this?

Probably.

HolQeD 8:1 included a "Maltz Online" section which reprinted some of Marc Okrand's comments in places like the MSN expertform newsgroup. One of the comments was the one answering the question "What time is it?" The relevant excerpt is

cha'logh Qoylu'pu
This is literally Someone has heard it twice or It has been heard twice. This is the Klingon equivalent to "It's two o'clock." Originally, this was a statement of time in the traditional Klingon system, but it is now also used for the 24-hour system.

[The "traditional Klingon system" is speculated about, but never quite explained.]
