John,
Thank you very much for a prompt reply!

I'm working with very the old version (Rbase 2.11) and have some concerns. Dear Vlad, Even R:BASE 2.11 will recognize your system clock when the time changes. The key is to make sure the time changes, then you have to exit and restart R:BASE. Daylight Saving Time Background ------------------------------- Under legislation enacted in 1986, Daylight Saving Time in the U.S. began at 2:00 AM on the first Sunday of April and ended at 2:00 AM on the last Sunday of October. But, the Energy Policy Act of 2005 extended Daylight Saving Time in the U.S. beginning in 2007 to begin at 2:00 AM on the second Sunday of March and end at 2:00 AM on the first Sunday of November. Here in the US, Year DST Begins DST Ends ---- ---------- ---------- 2003 April 6 October 26 2004 April 4 October 31 2005 April 3 October 30 2006 April 2 October 29 2007 March 11 November 4 2008 March 9 November 2 2009 March 8 November 1 Personal Computers ------------------ So, how does this effect our computers? Normally, during your operating system configuration you are prompted to "Automatically adjust clock for daylight saving changes" when selecting your time zone region. If this is checked, your computer's time will likely not change on March 11 without the latest Microsoft Daylight Savings Time Update: http://support.microsoft.com/gp/cp_dst Or, you could simply remove this setting by double clicking on the operating system clock, selecting the "Time Zone" tab, and remove the check for "Automatically adjust clock for daylight saving changes". Then, on March 11, make sure you change your time manually. Network Installations --------------------- Network administrators with many computers are likely taking advantage of running batch files to control the time on the workstations. You could run a batch file that sets the time to the server time. Then, each workstation will use the correct value. The batch file would consist of something like this: net time \\<server name> /SET /Y The /SET tells the workstation to use the time from the \\<server>, and the /Y tells it to answer "YES" to the prompt that normally occurs. The server time can also be set to update from a Web site server that stores an atomic clock value, like the NIST (National Institute of Standards and Technology), NASA (National Aeronautics and Space Administration), or the U.S. Naval Observatory. NET TIME \\<SERVERNAME> /SETSNTP:<SERVERNAME> /SET /Y The /SETSNTP option tells the computer to stay synchronized ALL THE TIME. You'll need to specify a server in your building that you want to set to. Address for NIST (192.43.244.18) Address for NASA (128.102.16.2) Address for U.S. Naval Observatory (192.5.41.40) Hope this helps! John
