timekeeping: Fix timezone update
commit 64ce4c2f (time: Clean up warp_clock()) breaks the timezone update in a very subtle way. To avoid the direct access to timekeeping internals it adds the timezone delta to the current time with timespec_add_safe(). This works nicely when the timezone delta is > 0. If timezone delta is < 0 then the wrap check in timespec_add_safe() triggers and timespec_add_safe() returns TIME_MAX and screws up timekeeping completely. The comment above timespec_add_safe() says: It's assumed that both values are valid (>= 0) Add the timezone seconds adjustment directly. Reported-by: Rafael J.
