After syncing with my computer I noticed that my calendar entries were off by an hour. Sounds like a problem with the Daylight Savings right?

So, I did a search and found lots of postings that said basically:

Confused: Why are my calendar appointments off by an hour?
Guru: Check your time zone and daylight savings settings on both computer and blackberry.
Confused: OK, I did that and it fixed the problem - thanks!
Other Confused: I have mine set to network time and still have problems.
Other Guru: Set to manual time and turn all daylight savings off and do everything manually.
Other Confused: OK, gave up on automatic time setting and have it working now.

Now in all (or most) of these conversations there seems to be the implicit understanding that you can turn on or off daylight savings handling on the blackberry. There were several ways suggested for how to do this, none of which appear to work on my 8100. The best I can figure is that I can set it to Mountain (-7) until PST hits which lies about my time zone for about 6 months out of the year in order to make sure that my handheld has the appropriate time shown on the display and the appropriate concept of universal time.

Am I missing something? Some advanced time zone option screen buried somewhere in the 8100 options?

This thread might have some additional background information that is helpful. Sounds like it might be a difference between your BB time zone and Outlook.

Thanks, but my question was about options on the blackberry related to daylight savings time. Are there any?

The threads I paraphrased all imply that there is a way to turn on or off DST on the blackberry, but I don't see any way to do that on my 8100.

i dont even know how to tell the phone to go get the real time from a server automaticly, I had to put it in myself.

Options > Date/Time > Date/Time Source > Network

I like straight to the point posts like this.

I was under the impression that when you have the phone set to check time "online" or "network," that T-Mo [or whomever is the carrier] periodically checks the time and updates the phone's indicated time.

With this process, I suspect RIMS thinking is that there is no need to have a daylight savings time switch, even in areas where DST is not practiced [Arizona?] since the time is updated through the carrier.

This is different then Windows XP, for example, where the PC/Windows does NOT check the accuracy of the clock. One needs a third party program like I have, AtomTime Pro.

I don't know that they considered the calendar time differences between those set in Outlook and the Pearl. Maybe a Google search on that issue might turn something up.

Maybe it has to do with whether one tells Outlook to "trump" the Pearl settings or vice versa.

Or perhaps the Pearl has to be set to Blackberry as the source for time?

Or the default time settings/increments in Outlook and on the Pearl have to be the same. as well as length of day?

Just thinking out loud. May not have answered your question.

Well you sure gave it the old college try!

I tried selecting Network time, but nothing really seemed to happen for a while (the time was different than the network time, but it didn't receive an update after like an hour) so I set it back. Maybe I should leave it on Network time for longer, but I don't trust the T-Mobile towers around here. Back when I had my T610 set to get the time from the network it kept going into some bizarre timezone and it was a pain to get the time back to normal. I eventually just turned off the network time.

At the time when I tried the Network time for an hour on the BB, I noticed that the network time was GMT as listed on the Date Options page. T-Mobile was obviously having one of their hiccups like they had back in my T610 days. That was when I decided - hey I'll try this Network time thing right now and see what hapens - but nothing happened for quite some time (the network was GMT and it was also 2 additional minutes off from the time I had in the BB, but it just stayed 2 minutes off on my original time zone for an hour or so).

Grumble - wish I could trust the Network time around here.

So it looks like I'll just have to switch to Mountain Time (-7) and swallow my purist indignation over not having a PDT (Pacific Daylight) setting...
