delete clones older than x days

Hi Guys,

I am trying to create a ps script that will be used to clone a VM and as part of the script only keep two instances of the clones.

This is the code i have at the moment but i am struggling to determine how create the condition to check for how old a VM is and delete a VM that is older than 2 days after a successful clone has completed.

#Date and Time

#VM Clone

New-VM -name "test-$now" -vm test -vmhost esx1.test.com -datastore datastore1

#

Any help would be great

Thanks

Dougie
