mysqldump seems to output utc time instead of local time at the end of dump

How to repeat:
I'm in Italy and it's now 2009-04-23 12:04

>mysqldump -u user --no-data dbname

-- MySQL dump 10.13  Distrib 5.1.34, for Win32 (ia32)
-- Host: localhost    Database: prototi_coge
-- ------------------------------------------------------
-- Server version	5.1.34-community


-- Dump completed on 2009-04-23 10:02:33

Thank you for the bug report. Please read the Manual at:



This option enables TIMESTAMP columns to be dumped and reloaded between servers in different time zones. mysqldump sets its connection time zone to UTC and adds SET TIME_ZONE='+00:00' to the dump file. Without this option, TIMESTAMP columns are dumped and reloaded in the time zones local to the source and destination servers, which can cause the values to change. --tz-utc also protects against changes due to daylight saving time. --tz-utc is enabled by defaul..."

Maybe I didn't explain the problem well:
the mismatch with dates does not happen in dumped data but on the last comment line where mysqldump outputs "Dump completed on xxxxxx". This date on my system is two hours before the current time.
This is not a big problem for sure, I just wanted to point it out, so that it can be corrected in a future release.

In mf_getdate the test for GETDATE_GMT was inverted, so by default you would get GMT time.  My patch reverses this again.

      The get_date() function in mysys interpreted the GETDATE_GMT option
      backwards, which resulted in the incorrect time being reported at the
      end of mysqldump. (Bug #44424, patch by Andrew Hutchings)
