RHEL 7.3 and 7.4 guest OS's system clock is unstable on VMware ESXi
A time offset happens whenever system reboot is initiated. The system clock is synchronized with a remote NTP server before rebooting the server.
The time offset happens even if both "constant time synchronization" and " major event time synchronization" have been disabled. ( The procedure to disable VMware's time synchronization is described in Erratic time issues on VMware based RHEL guests running ntpd . )
