Well, seconds have been used since the Babylonian time period. However, we also don’t know how carefully Harry measured the recharge time.

There are a lot of older units of time listed there, but none of them seem to fit.
Huh. That’s fascinating. I had apparently wrongly assumed that because it had the same division into 60 that it also was as old. Apparently not.
Carefully enough not to round it up to 3:55. Presumably, it’s within a second.
