NetBSD lust.misaligned.org 3.1.0_PATCH NetBSD 3.1.0_PATCH (LUST) #0: Tue Feb 13 22:33:31 MST 2007  src@lust.misaligned.org:/usr/home/src/cvs/netbsd/netbsd-3-1/obj/sys/arch/i386/compile/LUST i386
>Description:
My systems running under Canada/Mountain failed to reflect the correct localtime on March 11, 2007.

It would appear that Canada/Mountain wasn't updated to reflect the changes to DST:

bash-3.2$ zdump -v /usr/share/zoneinfo/Canada/Mountain | grep 2007
/usr/share/zoneinfo/Canada/Mountain  Sun Apr  1 08:59:59 2007 UTC = Sun Apr  1 01:59:59 2007 MST isdst=0
/usr/share/zoneinfo/Canada/Mountain  Sun Apr  1 09:00:00 2007 UTC = Sun Apr  1 03:00:00 2007 MDT isdst=1
/usr/share/zoneinfo/Canada/Mountain  Sun Oct 28 07:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 MDT isdst=1
/usr/share/zoneinfo/Canada/Mountain  Sun Oct 28 08:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 MST isdst=0

bash-3.2$ zdump -v /usr/share/zoneinfo/MST7MDT | grep 2007
/usr/share/zoneinfo/MST7MDT  Sun Mar 11 08:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 MST isdst=0
/usr/share/zoneinfo/MST7MDT  Sun Mar 11 09:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 MDT isdst=1
/usr/share/zoneinfo/MST7MDT  Sun Nov  4 07:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 MDT isdst=1
/usr/share/zoneinfo/MST7MDT  Sun Nov  4 08:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 MST isdst=0

NOTE: I'm not sure if everyone under the Canada/Mountain zone is affected by the new DST changes.
