2007 Canada Daylight Saving Time (DST) Extension

Details

Extended Daylight Saving Time (DST) for the following time zones in Canada begins in March 2007:
  • Atlantic
  • Mountain
  • Pacific
  • Yukon
  • Central
  • Eastern
  • Newfoundland

Solution

VMware has produced an update for these products affected by the new DST change:
  • VMware ESX Server 2.5.x
  • VMware ESX Server 3.0.x

The update has been incorporated into these product releases:

  • VMware ESX Server 2.5.4 Upgrade Patch 4 or later (build 38650)
  • Patch bundle ESX-9716732 for VMware ESX Server 3.0.0
  • Patch bundle ESX-3996003 for VMware ESX Server 3.0.1

The ESX Server downloads pages are at:

VMware recommends upgrading to a supported version of ESX Server. Patches are available from the respective download pages. 
 
Checking an ESX Server host for installed updates:
 
ESX Server 2.x patches are cumulative and are referenced by the build number. The current build number is listed in the management interface (MUI), or in the display using VirtualCenter 1.x. Optionally log on to the service console and use the command vmware –v. For example:

[root@esxhost]# vmware -v
VMware ESX Server 2.5.4 build-38650 

To check for installed bundles on an ESX Server 3.x host, use the following command on the service console:
 
[root@esxhost]# esxupdate query
 
The output should contain the corresponding bundle for your specific version of ESX Server 3.0.x. 
 
Confirming timezone updates contain new DST data:
 
After the system has been upgraded to a patch with timezone changes, make sure /etc/localtime reflects the changes using the following steps:
  1. Check that the zoneinfo file for the ESX Server host location has the correct changes reflecting the new DST dates:

    [root@esxhost]# zdump -v /usr/share/zoneinfo/<specific zoneinfo file> | grep 2007

  2. Compare the output from step 1 with what is currently in /etc/localtime:

    [root@esxhost]# zdump -v /etc/localtime | grep 2007

  3. If the output from /etc/localtime is not correct, copy the specific zoneinfo file from /usr/share/zoneinfo to /etc/localtime.

    [root@esxhost]# cp /usr/share/zoneinfo/<specific zoneinfo file> /etc/localtime

    If prompted to overwrite /etc/localtime, type yes.

    Note: It is not necessary to reboot.

  4. Check that /etc/localtime has the correct DST timezone dates.

    [root@ esxhost]# zdump -v /etc/localtime | grep 2007
