DFS Replication from Multiple Time Zones

Hello,

Currently I am replicating data from 3 diffreent time zones (branch offices) back to our Corp office which is in CST. I have three servers in Corp setup to match those three time zones.

I am planning to consolidate those 3 boxes into 1 DFS server that will reside in our Corp office.

Question: will there be any possible issues with the file time stamps, resolution of which file would get overwritten in the case of conflict etc. if Branch office DFS server's time will not match with Corp DFS server's time?

Thanks

John
