Sinan, It's not there, but it's not terribly complicated to accomplish. Just take a look at TimeSyncC and TimeSync32kC, and based on those, come up with your TimeSyncMicroC. As far as I can tell, this is the only file you'll need to cook for yourself, you don't need to touch anything else.
A couple of notes: - On the iris, the interface provided by TimeSyncMessageC that gives you microsecond precision packet-level timesync is called TimeSyncAMSendRadio. - You can get microsecond-precision local time from LocalTimeMicroC, however, time will stop when the mote goes to sleep. You will need to keep the MCU awake all the time to get FTSP to work properly. There are a couple of different ways to do this, for example by having a component that provides McuPowerOverride and the lowestState function always returns ATM128_POWER_IDLE. You'll need to wire this component to McuSleepC.
