Did somebody check Rbase compliance with the upcoming Daylight Savings
Time event?
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

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:

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 U.S. Naval Observatory (192.5.41.40)
Hope this helps!
