MSBuild MSBuildCommunityTasks Task Time - msbuild

Question

I have a MSBuild project and I want the current date to be added to a zip file that I am creating.
I am using the MSBuildCommunityTasks.
<!-- Import the CommunityTasks Helpper -->
<Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" />
On the website http://msbuildtasks.tigris.org/ I can see a task called time. I have not been able to find doc on how to use Time.

Answer 1

In msbuild 4 you can now
$([Namespace.Type]::Method(..parameters…))
$([Namespace.Type]::Property)
$([Namespace.Type]::set_Property(value))
so I am using
$([System.DateTime]::Now.ToString(`yyyy.MMdd`))
those ticks around the format are backticks not '

Maslow's answer is correct (I can't comment on it or I would); I would only add to it that you have to be careful when implicitly calling System.DateTime.Parse.
A parsed string value like $([System.DateTime]::Parse("1970-01-01T00:00:00.0000000Z") doesn't seem to end up with a Kind of DateTimeKind.Utc.
But you can use nested property functions to make it work; like this (to get the Unix timestamp):
$([System.DateTime]::UtcNow.Subtract($([System.DateTime]::Parse("1970-01-01T00:00:00.0000000Z").ToUniversalTime())).TotalSeconds.ToString("F0"))
