How is CURRENT defined for a UDT endpoint?

Hello, I am looking to create an alert for certain endpoints down in Solarwinds via UDT. When navigating to a node, I can see the details here:

However, via the UI, under alerts I cannot find the variable last seen. I've queried the Orion.UDT.Endpoint table and see the LastUpdate field, but it shows a date/time instead of the value "CURRENT". How does Solarwinds define current? Also, how can I use this in an alert?

is the LastUpdate field the current date in UTC?

Yes, it does.

I'm trying to understand what the calculation is.

I would think that if last field update is less than the last poll, it would no longer be current and it will appear as last seen. As you can see, the last update are all on the same time so that means it was gathered via the layer 2 Polling all at the same time for the particular device.
