Introduce a type representing a specific point in time. We could use
the Ktime type but C's ktime_t is used for both timestamp and
timedelta. To avoid confusion, introduce a new Instant type for
timestamp.

Rename Ktime to Instant and modify their methods for timestamp.

Implement the subtraction operator for Instant:

Delta = Instant A - Instant B
