#### Local build testing
- I built this PR locally for my native architecture, (i686)

#### Change description
On i686, `time_t` is a 32 bit integer. In `openntpd`, an addition of two `time_t`s is performed, leading to an integer overflow. This code is part of the constraints logic of openntpd. When the bug triggers, all time sources will be marked invalid.
