Daylight Saving Time 2007 (Y2K7)

Congress has decided that we should all get up an hour early tomorrow. I kind of wonder who is making money from this little experiment. The one thing that I have noticed so far is that the summer gasoline prices are coming about three weeks early. And it is just an experiment: the Energy Policy Act said that they would evaluate the "energy savings" and possibly change it back.

We have spent a few months planning and preparing for this computer software change. Every system and application seems to have a different way of computing wall clock time. Windows, Exchange, Java... Kronos, Exchange, PowerChart... All this work patching and upgrading systems and on Monday everyone else (hopefully) will say, "What's the big deal, nothing happened!"

But even yesterday, vendors were giving us notice that their software is not ready. The GE PACS software has their own copy of Java that needs to be patched on workstations. I think that GE was already trying to tell us about this one, but the critical applications that are closest to actual patient care are supported by Clinical Engineering, not IST.

I've recently learned a few things about time zones and Java... but who is Olson?

There is no energy savings...

I had it easy. (At least I assume so, I'll find out tomorrow or Monday, I suppose...) I have planned patching every February and July, the HPUX patch was available some time ago, and dropped right in. HP also pathed their Java long before I bothered to look at it for the patch cycle.

The only problem I really had was that Peoplesoft bundled their own Java, and rather than fix it, they instructed people to use the OS Java. The Peoplesoft team tried the fix after I patched, but it didn't work. Turns out Peoplesoft also wanted a Java Addon installed, which people forgot to tell me before hand. This was an extra few hours of my time between listening to the Peoplsoft team attempt to explain what was going on, figuring out what they really meant, and adding the additional Java Addon.

I'm all for getting rid of Daylight Saving all together... (And timezones, for that matter.)

I got out alive, and you?

There were some heart monitors at DeGraff that had the wrong time, but I don't think that anyone died. (They don't let us touch systems that have humans as peripherals, so Clinical Engineering gets credit for this one.)

Windows Mobile devices were a problem in some cases because we don't support them (officially) and they didn't read my email about patching them three weeks ago.
