This translation is not the same -- before FromUTCExploded() was run a single
time, whereas now it is run on each invocation of the function.

And in fact neither is correct, explained the problem here:
https://bugs.chromium.org/p/chromium/issues/detail?id=657903

I will fix this (https://codereview.chromium.org/2441713002/) so won't require
any changes in this CL.
