Did you genuinely find it difficult to parse the comma delimited representation near the bottom of the article? Just curious. It seemed very natural to me, a minor variation on British style thousand separators.

Maybe ':' would be a more familiar separator because of hours, minutes and seconds (yeah, hours don't go up to 60, but whatever).

Myself, not really given the context in the article. If I was shown this without context it would be pretty confusing. Using : would be better as or would suggest clock which is base 12 plus base 60... Letters are clearer still if given the base identifier - commonly subscript number.

The suggested notation would make for interesting puzzles.
