The remote and consolidated databases have different timestamp precisions, and a timestamp value with a precision higher than the lower-precision side was used for conflict detection purposes. Consider using the -zp option

Error code 10021
Error constant SUSPICIOUS_TIMESTAMP_DIFFERENCE
Probable cause

An upload conflict is detected based on a tolerable timestamp difference while the -zp command line option is not used. If you decided not to align precision on the databases involved in your synchronization system, you may use the -zp swith to start the MobiLink server. If the command line option is used, MobiLink server will tolerate conflict caused by timestamp differences smaller than the lower precision among the two databases.
