Does XBEE nodules have synchronized clocks?

I have recently purchased several units of Digi XBee PRO S3B. I need to use a universal clock, which is synchronized across the whole network.

Does anybody know if these modules support such an option? If so, how do I “ask” the module what is the time?

Thanks.

While the radios offer a synchronous sleep function, they do not support that kind of function.
