Setting properties in Aria Operations with timestamps in seconds will result in "200" response and the appearance that API was successful, however Properties will not show up on objects.
vRealize Operations 8.10, Aria Operations 8.12 and Above
Aria Operations requires timestamps to be in milliseconds since 8.10. Validation cannot be set as it would cause backward compatibility of the API to fail.
Convert timestamps in API code to milliseconds by multiplying by 1000
Example:
$contentprop.timestamps = [double]::Parse((Get-Date -UFormat %s))
becomes:
$contentprop.timestamps = [double]::Parse((Get-Date -UFormat %s))*1000
