Re: Time Zone and Date problems - TxP changing dates in the actual DB

Mary

Is this what you are looking for? I ran it from the phpAdmin SQL tab.

CONVERT_TZ(‘2007-03-11 2:00:00’,‘US/Eastern’,‘US/Central’)
2007-03-11 01:00:00

CONVERT_TZ(‘2007-03-11 3:00:00’,‘US/Eastern’,‘US/Central’)
2007-03-11 01:00:00

I’m not conversant in MySQL, so I don’t know if returning the same result is good, bad, or in-different.

  • The queries return the same for both a dev. 4.0.x install and for my crockery test site (Textpattern version: 4.1.0 (r2767). Both are hosted on Dreamhost.
  • With the 4.0.x version there is not “Daylight” savings check box.
  • With the crockery install the “Daylight Savings” is checked. When I uncheck it and save, it reloads checked.
  • To work around I have set both to GMT – 6:00.

Thanks
Mike

Re: Time Zone and Date problems - TxP changing dates in the actual DB

See MySQL Server Time Zone Support

Mike, your result appears to mean that it is indeed a MySQL problem (see above).

Nathan, if you run this:

SELECT COUNT(*) FROM mysql.time_zone_name;

what do you get?

Re: Time Zone and Date problems - TxP changing dates in the actual DB

We can’t really tell whether you have the same problem as Mike, since your host is protecting that table from view. If I were you, I would contact my host, describe to them the problem, refer them to that MySQL manual entry (see above) and ask if that might be the cause.

Re: Time Zone and Date problems - TxP changing dates in the actual DB

Thanks Mary. I just returned to work after vacation, so I’m playing catch-up, but will follow up on your feedback as soon as I can.

Thanks again

Mike
