 If both chrony and TimeSync sources are enabled simultaneously, you can mark one as **prefer** which sets the other source as a backup. Because NTP services do not update the clock for large skews except after a long period, the VMICTimeSync will recover the clock from paused VM events far more quickly than NTP-based tools alone.
 
+By default chronyd accelerates or slows the system clock to fix any time drift. If the drift becomes too big, chrony will fail to fix the drift. To overcome this the makestep parameter in **/etc/chrony.conf** can be changed to force a timesync if the drift exceeds the threshold specified.
+ ```bash
+makestep 1.0 -1
+```
+Here, chrony will force a timesync if the drift is greater than 1 second. To apply the changes restart the chronyd service.
+
+```bash
+systemctl restart chronyd
+```
