This can be observed for example when a FAT-formatted -volume is compared against an NTFS volume as frequently happening -with USB memory sticks.

In both cases Windows uses -the current DST status as well as current time zone information for -its calculations. Consequently the result of this comparison is -dependent from current system settings and in particular file times -that used to be the same can show up as different after a DST switch.</FONT></P> -<P STYLE="margin-bottom: 0cm"><BR> -</P> -<P STYLE="margin-bottom: 0cm"><FONT FACE="Tahoma, sans-serif">For a -detailed discussion about this issue refer to: -<A HREF="http://www.codeproject.com/KB/datetime/dstbugs.aspx">http://www.codeproject.com/KB/datetime/dstbugs.aspx</A></FONT></P> -<P STYLE="margin-bottom: 0cm"><BR> -</P> -<P STYLE="margin-bottom: 0cm"><FONT FACE="Tahoma, sans-serif"><B>Solution:</B></FONT></P> -<P STYLE="margin-bottom: 0cm"><FONT FACE="Tahoma, sans-serif">Luckily -FreeFileSync users need not to worry about this issue.
