There is a way to determine when a computer was last rebooted. This information is gathered by default, by Inventory Solution. The inventory policies that gather this information are Collect Full Inventory and Collect Delta Hardware Inventory. You can create a gather inventory task that specifically targets these data classes. This would allow you to be more aggressive reporting this data.
The steps to do this are:
You can now run this against your endpoints as needed. You can then query the Inv_OS_Operating_System table for the Last Reboot Time.
