Extend delay for alert resume via powershell

Question

I have a powershell script to suspend and resume alerts.

What I need to do is tell the system to resume alerts an hour in.

The command I'm using is...

Invoke-SwisVerb $SWIS Orion.AlertSuppression ResumeAlerts @($entityUris, [DateTime]::UtcNow) | Out-Null

...and I've tried to use .addminutes  to the date time but I'm obviously getting it wrong because on execution, the node is unmuted immediately.

Any suggestions please?

Solved. There was a third variable I didn't know about.

Basically - @($entityUris, $now, $later)
