[LTP] [PATCH] clocks/invaliddates.c: Remove outdated clock time setting

[Yang Xu]

For CLOCK_REALTIME, attempting to set the time to a value less than
the current value of the CLOCK_MONOTONIC will trigger a EINVAL error
since linux 4.3. Remove zero and also increase threshold for delta with
personal experience.
