220.127.116.11.12.1 Remain current with time zone changes
If the time zoning rule changes, those that use the old rule are obsolete. In order to keep up to date, it is necessary that your system uses the current time zones information. Ensure that your OS is using the latest time zoning information. The latest updates or updates for most platforms prepare your system for time changes.
Verify the website of your OS supplier for an updated version that takes time changes into account. If a new fix is available, please feel free to browse and use it to substitute the contents of your current time zoning charts. When you are not sure whether designated time Zones are available that are used either as the server's time zone preference or by Client machines that define their own time zoning, verify that your time zoning charts are empty.
If the following prompt is displayed, the system will determine whether the timezone name containing chart has any rows: ....; A zero counter means that the chart is empty. No one can use designated time zones in this case, and you do not need to refresh the spreadsheets. If the counter is greater than zero, it indicates that the chart is not empty and that its content is available to assist with designated time zones.
If this is the case, you should refresh your time zoning charts so that everyone who uses designated time zoning receives accurate results. This example uses suitable one-hour daylight saving time 2007 changes in the United States on March 11 at 2:00 a.m. The test uses these two queries: "2007-03-11 2:00:00", "US/Eastern", "US/Central"; "2007-03-11 3:00:00", "US/Eastern", "US/Central"; The two time data indicate the time when the daylight saving time changes, and the use of designated time zone require the use of the time zoning.
You want both requests to produce the same results (the duration of the entry, translated into the corresponding value in the time zones "US/Central"). You would see a wrong outcome like this before you update the time zoning tables: 2007-03-11 2:00:00','US/Eastern','US/Central';'2007-03-11 3:00:00','US/Eastern','US/Central'; After refreshing the table you should see the right result:'2007-03-11 2:00:00','US/Eastern','US/Central';'2007-03-11 3:00:00','US/Eastern','US/Central';
