DST Change only Three Weeks Away…

Those of you who think the blog bug is being neutralized in one Laura Gekeler, think again… I will be here.

You haven’t heard from me because we have a number of open support tickets of a serious (to us) nature. Last week I even missed the VistaSWAT call which I knew would discuss this DST hotfix topic, but I was engaged in tracking down an SCT Banner / Bb Vista sync problem …another posting.

So what’s up with this DST time issue? We have a Support Bulletin released Jan. 29th telling us there’s a Hotfix release candidate for Daylight Savings problems. A release candidate? Three weeks from the event horizon? You’ve got to be kidding. Blackboard… come on!

I am NOT installing a release candidate in production. I am NOT installing a release candidate in development and believing I can then jump to the final release for installation into production. Hello?

Why are we even dealing with daylight savings time again?

What are other DST symptoms in your environments? I see this one where assignments set up now which are due on March 9th get assigned a due time an hour later than what you set it, as opposed to assignments on this side of the date shift. I have to assume this occurs in other date sensitive tools as well.



The calendar tool has its own problems in addition to daylight savings.

One thought on “DST Change only Three Weeks Away…

  1. Prior to the 2007 DST fixes we applied to various software, one of the things I did was look at how dates were stored.
    I found they were inconsistent. In some cases they were stored as Oracle dates. In others they were stored as epoch. It was the epoch dates which suffered problems.
    To write the time, the application has to figure out the number of seconds between the time now and a future time. The complex rules make that quite interesting. It sounds like something in the logic was goofed.
    I am surprised Oracle or Java does not determine the time for applications built on top of them? That way Blackboard doesn’t need to so much know how to calculate the time as make a call which figures it out. Also, they can point to Sun or Oracle as screwing it up. 🙂
