Interesting idea. Certainly for the internally hosted SPs (and IdP) they all sit in the same vSphere datacenter - so I assume the time sync is correct across all windows servers.</div>

I will ask our Core team (who provision VMs for us) to confirm this for me though.</div>

I'll also ask our Library team to monitor for any eResources patterns, and check in with those SPs to see what their time sync arrangements are.</div>
