type of "tst"

[ckrey]

according to the booklet, "tst" is an integer (e.g. "tst":1702579142).

But Greenwich devices deliver "tst" as a string (e.g. "tst":"1702528760").

This causes validation for Greenwich devices to fail

I don’t consider this a problem as the devices are a dying breed. Admittedly it’s a short term issue which we might work around by decommissioning Greenwiches earlier.
