[Skiboot] [PATCH 09/13] mktime: fix off-by-one error calling days_in_month

[Stewart Smith]

>From auditing all the mktime() users, there seems to be only a *very*
small window around new years day where we could possibly return
incorrect data to the OS, and even then, there would have to be FSP
reset/reload on FSP machines. I don't *think* there's an opportunity
on other machines.
