Time Change Information

Congress has advanced the date on which daylight savings begins by three weeks to the second Sunday of March (March 11, 2007) and delayed the change back to Standard time by one week to the first Sunday in November (November 4, 2007). If you are a Renalog RM user, a Microsoft Windows XP patch must be installed on the Renalog RM computer to correct the daylight savings change dates. If the patch is not installed the time on the Renalog RM computer will be off by one hour for the three-week time period before the spring and one week before the fall time changes.

Note: This patch will not work for Renalog 3 computers.

Microsoft provided a patch, labeled TZEDIT.EXE, to correct the daylight savings time changes, the Minntech instructions describing the necessary modifications are included on this page.
