Sometimes it is hard to get your settings right. We don't change time here, we stay on Eastern Standard Time all year round. But do you think I can get Blogger to admit that? No. Choosing the EST time setting means that it assumes I am now on EDT. Changing to CDT would re-timestamp all the entries in the blog. So for half the year I will either post at the wrong time or have to remember to change the time whenever I post.
Sometimes living outside the box has its challenges (at least Windows allows you to choose whether or not to adjust for Daylight Savings--although you can't actually save daylight, the Earth turns at the same rate no matter how we set our clocks--Time).
