DB2 Replication - synchtime

[Ben]

I changed the system date to year 2011 for testing. When I changed the
system date back to current, I found that the SYNCHTIME in table
ASN.IBMSNAP_SUBS_SET recorded the date of year 2011. The SYNCHTIME did not
refresh to current date even I had performed the full refresh.

Do you have any ideal to change the SYNCHTIME back to current date?

Thanks!
