The FTSP paper refers to a TinyOS 1.x-based implementation, and that one does microsecond-precision timestamping on micaz.
In TinyOS 2.x, the HIL only requires millisecond-precision timing, and that's what FTSP relies on. In that case, 1 jiffy is about 1 millisecond (1/1024 second, to be specific). There's also a 32kHz FTSP implementation in the repo -- which only works on the platforms that offer 32khz timestamping. Currently, there's no FTSP implementation in TinyOS 2.x that does microsecond-precision synchronization. It's not that hard to create one, though: you can use the 32khz implementation as a starting point. Let me know if you want to do that, and I can help you out with the details.
