Description:
If --init-file=file.sql is supplied and file.sql contains a query that inserts a date using the NOW() function, the date reported is '1970-01-01 11:00:00' and not the actual date/time.

How to repeat:
Add the following line to the my.ini file (assuming default install).

init-file="C:/Program Files/MySQL/MySQL Server 5.0/Server-init-file.sql"

create the file "C:/Program Files/MySQL/MySQL Server 5.0/Server-init-file.sql" with the following contents:
-- Start

CREATE DATABASE IF NOT EXISTS init_file;
CREATE TABLE IF NOT EXISTS init_file.startup ( startdate DATETIME );
INSERT INTO init_file.startup VALUES ( NOW() );

-- End

Now start the server.

I forgot to add, now check the table "init_file.startup"

  Bug#23240 --init-file statements with NOW() reports '1970-01-01 11:00:00'as the date time
  
  - 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.

From review on IRC:
1. Highlight that the error happens in bootstrap and investigate if separate --bootstrap test needed.
2. is THD::end_time necessary?
3. Investigate if possible to move set_time/end_time into mysql_parse
