- Starting time of a query sent by bootstrapping wasn't initialized
  and starting time defaulted to 0. This later used value by NOW-
  item and was translated to 1970-01-01 11:00:00.
- Marketing the time with thd->set_time() before the call to
  mysql_parse resolves this issue.
- set_time was refactored to be part of the thd->init_for_queries-
  process.
