"Time Left:" Message Broken

[Kerin]

The purple message you get in the chat log if you try to use a spell that's still on cooldown, "Time left: xxx" is now saying:

"Time left: 1 Jan, 1970 0:00:34"

Clearly this is a timestamp value that's set to nearly zero and not a valid value, presumably a time calculation of some sort has gone awry. No idea when I broke, I only just noticed it while doing the monthly High-Tier.

Note the 'seconds' value seems to be what should be being shown, the rest of it of course is just wrong.
