And You Thought The Early Daylight Savings Chaos Had Passed...

by Lawrence D'Oliveiro on Mar 30th, 2007 @ 10:24pm It's not just that Linux and Unix use UTC time, but that they have a systemwide timezone database (zoneinfo) that (nearly) all apps use, instead of inventing their own systems for keeping track of timezones and daylight saving. Thus, a single update to this database is generally enough to get your apps to work with the updated rules. Also, it's very easy to test the rules, using standard tools like the date command, to ensure that they're correct beforehand.

by simon on Mar 31st, 2007 @ 6:41am even since windows xp, there is a time synchronization of the system to 1 of the 2 time server existent, which, if u set correct time zone on pc problem should be fixed only on the time servers, pretty easy job, but if pc is not connected to internet, or time synchronization is not enabled, all you need is to correct time yourself in the morning after pc will push time ahead 1 hour, since is programed to do so.
for win 2000 and early windows systems, users should check out and change system time (really easy job) but again, people this days, tend to let them selfs controlled by technology, and not vice-versa..

ps. just trust better the wrist watch you carry or just use this problem as argument on being late on meetings
by David Dove on Mar 31st, 2007 @ 10:02am Folks, Just about ALL servers use UTC time and most workstations have an NTP client installed as part of the OS.

I just remediated all of the systems for a branch of Connecticut's state government prior to DST2007. The CLIENT must have the DST patch (which modifies the timezone files - just like Unix) or the CLIENT will misinterpret the date and time. It does not matter which OS the client is running, it is the workstation's responsibility to interpret the data.

As for the calendar entries, many vendors (including Microsoft) provided "rebasing" tools. Microsoft's tool was a joke since it required you to have dedicated workstations with priv'd access cycle through EVERY user's mailbox. My first run for 2000 people took over 12 hours.

The performance of the tool improved one week before DST2007 but by that point it was too little too late.

I used to Live In Lousianna and hated the switch! I hope the law makers of out state dont start daylight savings time.
