- Starting time of a query sent by file bootstrapping wasn't initialized
and starting time defaulted to 0. This later used value by the Now-
item and is translated to 1970-01-01 11:00:00.
- marking the time with thd->set_time() before the call to
mysql_parse resolves this issue.
(fixed bug #2526 "--init-file crashes MySQL if contains large select")
Such checking usually works in send_ok, send_eof, but in this case large
result causes interim flushing.
