* if long is int64_t and time_t is int32_t, "(time_t) MY_TIME_T_MAX"
  results -1 and server_start_time is always parsed as exceeding limit.
  So, use TIMESTAMP_MAX_VALUE which is INT_MAX32.
* if time_t is int32_t, comparsion with TIMESTAMP_MAX_VALUE is always
  true here.  So, limit the comparsion to other cases.
