In a Canadian location observing DST, a single Vista setting supports both 1987–2006 and post-2006 time stamps, but mishandles some older time stamps
Older Microsoft Windows systems usually store only a single start and end rule for each zone, so that the same Canadian setting reliably supports only post-2006 time stamps.
These limitations have caused problems
For example, before 2005, DST in Israel varied each year and was skipped some years
Windows 95 used rules correct for 1995 only, causing problems in later years
In Windows 98 Microsoft marked Israel as not having DST, forcing Israeli users to shift their computer clocks manually twice a year
The 2005 Israeli Daylight Saving Law established predictable rules using the Jewish calendar but Windows zone files cannot represent the rules' dates in a year-independent way
Partial workarounds, which mishandle older time stamps, include manually switching zone files every year
Microsoft Windows keeps the system real-time clock in local time
This causes several problems, including compatibility when multi booting with operating systems that set the clock to UTC, and double-adjusting the clock when multi booting different Windows versions, such as with a rescue boot disk
In 2008 Microsoft hinted that future versions of Windows will partially support a Windows registry entry RealTimeIsUniversal that had been introduced many years earlier, when Windows NT supported RISC machines with UTC clocks, but had not been maintained since.
An interesting effect can be observed with file time properties
The file system stores the file with a time stamp according to its setting of GMT, but displays it corrected to local - or seasonal - time
When a file is copied from the hard disk onto separate media, its time will be set as the one normally displayed
If the time adjustment is changed, perhaps automatically (Daylight saving) or if the user prefers a different time zone, then look again at the time of the original and its copy - there will be a difference
Often, due to interim time updating, the difference will not correspond exactly to the adjustment and be a few seconds different
This may be verified (without having to wait for the next equinox) by: copying a file, remove the media, adjusting the time zone options, reconnect the media, view the details of the file and its copy
This effect needs to be in mind when trying to determine if a file is a copy of another.
Metric time is the measure of time interval using the metric system, which defines the second as the base unit of time, and multiple and submultiple units formed with metric prefixes, such as kiloseconds and milliseconds
It does not define the time of day, as this is defined by various time scales, which may be based upon the metric definition of the second
