GoDaddy: Certificates issued with validity periods greater than 398-days

Not a huge story here - seemingly a misunderstanding about timezones, but the CA/B baseline requirements have this to state, which seems pretty clear to me:

> By convention, this document omits time and timezones when listing effective requirements such as dates. Except when explicitly specified, the associated time with a date shall be 00:00:00 UTC.

Personally it seems odd to me that you'd assume such a change would kick in at midnight Arizona time, unless for some reason you thought Arizona was the centre of the PKI-universe...
