Condition not checked correctly

Question

I have a script in the condition "If PowerShell script returns true". For some reason the conditions in the script is not evaluated correctly.

Condition

Script

Log

As you can see, the log is supposed to be written only when the condition is met. I Don't know why the condition was met when the log clearly show that DisableDate is Friday, August 07, 2015 4:00:00 PM and Today is Tuesday, August 04, 2015 7:48:40 AM.

Hello,

The [System.DateTime]::Now method returns a DateTime structure that represents the current time. In your script, you use the DateTime property of this structure. In PowerShell, this will get you a string representing the date in text format, for example, Wednesday, August 5, 2015 3:53:36 PM.

The same is with the 'account disabled' date. $Context.TargetObject.Get($disableOn) will get you a DateTime structure representing the date when the user must be disabled. However, if you use $Context.TargetObject.Get($disableOn).DateTime, you will get a string representing the same date.

Thus, on the following line, you are comparing text strings representing the dates instead of actual dates: if ($disableDate -le $today).

To remedy the issue, remove the .DateTime part on the following lines:

$disableDate = $Context.TargetObject.Get($disableOn).DateTime
$today = [System.DateTime]::Now.DateTime

Also, [System.DateTime]::Now returns the date/time in local time, but $Context.TargetObject.Get("<DateTimeAttribute>") returns the date/time in UTC time, so your script doesn't take into account time zones. To remedy this, instead of [System.DateTime]::Now use [System.DateTime]::UtcNow:

$today = [System.DateTime]::UtcNow

Thank you! $Context.TargetObject.Get($disableOn) was returning the time in the local time zone (as entered), so I switched the UtcNow back to Now. Works fine now.
