Daylight Saving Time

What is it? Where did it come from?
All you ever wanted/needed to know about DST, click here. If you just want to make sure your system is O.K., READ on...

Now we are going to use Javascript to check DST settings on this computer.

JavaScript is required to check your DST settings!

Now we are going to use JavaApplet to check DST settings for your Java Subsystem

If your DST settings are correct, you are Done.

If not, For Windows XP/Windows 2003 and Vista go to:

For Windows 2000: Download/Save/Run This Registry Update

For Windows 98/ME: Download/Save/Run This Registry Update

If you use calendar features in older versions of Outlook (pre-2007), or similar software, you may need to get an update for them.

If your PC clock is slower/faster by more than half an hour, you should correct that.

Unfortunately each system/OS is different. However all need/should use NTP. We have 3 NTP servers: (Stratum 1 CDMA digital cellular telephony systems) (Stratum 2) (Stratum 2)
If your system cannot use NTP and it is looking for "daytime" or "time", you can use:

Most computer systems, and a number of other devices such as PDAs, Webcams, VCRs etc. use Universal Time internally and work out local time using a list of rules. Unless the rules are updated, the computer clocks will be an hour wrong for most of March. This may cause problems ranging from email apparently arriving before it was sent, to missed appointments or missed flights. (I for one always set my watch from my computer, since NTP keeps it accurate to a fraction of a second).

Y2K Revisited(DST changes)

Returns the number of non-leap seconds since whatever time the system considers to be the epoch.
On most systems the epoch is 00:00:00 UTC, January 1, 1970 a prominent exception being Mac OS Classic which uses 00:00:00, January 1, 1904 in the current local time zone for its epoch.
