Setting time on ESXi hosts through PowerCLI

So you go and build your new ESXi hosts, set NTP, but notice your time is still off. Did you know you can set your ESXi host time through PowerCLI?

After connecting to a host, you can set the time with the following commands. Always make sure you use UTC time when setting the time on your host as ESXi does not use timezones.

$t = Get-Date
$dst = Get-VMHost | %{ Get-View $_.ExtensionData.ConfigManager.DateTimeSystem }
$dst.UpdateDateTime((Get-Date($t.ToUniversalTime()) -format u))


And there you go. Now your ESXi hosts will have the same time as the machine you ran your script on, so just make sure that machine has the correct time.

And on why I have not blogged in a while, well that is another blog post.
