No. The EXTINTx function (these inputs are configurable for multiple purposes) that is only available on FTS (Frequency & Sync) products is using these for feeding in a reference frequency. > I've never found a good list of which products are FTS.

You must not have been looking very hard, the uBlox web pages are one of the easier ones to navigate when it comes to these things. Anyway, I've posted a link to the document containing that list some time ago already, here it is again: https://www.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_%28UBX-13003221%29.pdf Timestamping is actually supported on all firmware versions and only the M8F variant has FTS firmware. Due to the way the messaging works you only get two measurements per second, for the falling and rising edge of the same input.
