Confused by Date and Time stamps changing

I've long noticed odd switching of the date and time stamp on post to the forum.
Just wondering if anyone understands why the date and time stamps on post change?

It's not a big deal. Just a point of curiosity. :?

As an example. I live in the eastern time zone. Today I made a post on May 18th at 21:53 eastern time. However, the time stamp on the post showed the date/time of the post as May 19th at 1:53. Four hours into the future. Not five hours into the future to match GMT of May 19th at 2:53 nor matching my local time in the eastern time zone. The time stamp matches someplace west of London, someplace in the middle of the Atlantic west of Greenland. A TZ in the middle of no where.

Then if I log out of the forum. Leave the forum web page and then return to the forum. But don't log in. The date and time stamp on my post has changed to an earlier time. Actually the date and time stamp on the post now matches the Pacific time zone - showing my post as having been posted on May 18th at 18:53. Which makes sense because T-USA is located in San Francisco. But, nevertheless, an odd shifting of 7 hours on the date/time stamp as originally marked. But if I log in again, then the date/time stamp changes again, back to the date and time stamp originally marked on the post. Odd.

But, why doesn't the date and time stamp match Pacific time or GMT at the time of the post?
Why does the date/time stamp match some odd TZ in the middle of the Atlantic, but only when logged onto the forum?
Why does the date/time stamp match Pacific time zone date/time but only when not logged in?

I've never noticed this time shifting on post made on other forums. Where the time date/time stamp on a post either matches GMT at the time of the post or matches the time zone where the forum server is located and the date/time stamps don't change from the date/time originally stamped on the post.

Typing this as my inspiration and curious fellow traveler my son's cat, KC, attempts to lay on my lap interfering with my ability to reach the keyboard on the laptop. :)

Perhaps it's caused by the magic dragon dust used to make the Tenkara rods. Time space distortions effected by the unnatural effectivness of the higher than normal fish catching rates. ;)

When you log in, the time switches from PST to the time specified in your user control panel>board preferences>edit global settings.

You can leave the time somewhere east of Greenland or change it to EST pretty easily.

Thanks Chris,

I knew there had to be an explanation for the odd date/time switching. I almost never look at the settings in UCP, probably set to default since joining the forum and just never noticed the time settings or at least don't recall seeing it. Other forums I frequent don't have a time setting. :oops:

Anyway, I checked it and it was set to UTC with day light savings time turned off. Thus, because we are now on summer time, I got a time stamp for an hour west of London, same as UTC or GMT, so I got the odd 7 hour time shift and not the 8 hour shift between UTC vs PST. Setting preferences to day light savings enabled and to my local time zone, eastern UTC -5, helped. But the date/time between being logged in or not now shifted by 3 hours not by 7 hours as it was doing previously. In the end I found that what I like best is to set my board preferences to PST, UTC - 8. Now whether I am logged in or not, the date/time stamp doesn't change and it should remain ok when we switch time again in the fall. Now it is easier for me to more quickly spot new post. :D

KC and I will now find something new to be curious about or just go fishing together in the stream in front of the house. 8-)

I'm glad Chris explained the time settings. Sometimes I keep these things straight, but not always. The other day I went downtown for a talk at 7 Wednesday. I was even early, except that the talk is next week Wednesday! :( Well, technically I suppose I was early. All these new gadgets, like programmable calendars and such, are supposed to help me keep these things straight and usually do, but not always. ;)

Chris, thank you for clarifying this. Actually, that's one thing I had not been able to figure out when managing this forum. I tried setting it up to PST time on the admin panel, but that didn't work I guess. Thanks for sharing your knowledge on that.
