Timestamp inconsistency before/after compression

[LinZhihao-723]

Bug

When compressing a log event with a large timestamp, the decompressed timestamp is inconsistent with the original one.
Before compression: 3924-03-28 10:17:41.891
After compression: 2170-07-29 11:34:00.762
With further explorations, it was believed that this was caused by the execution of the following line:

clp/components/core/src/clp/TimestampPattern.cpp

Line 733 in c158852

auto timestamp_point = date::sys_days{year_month_date} + std::chrono::hours{hour}

It seems like the nanosecond precision causes the timestamp overflow; by removing line 737 the bug would be solved.
