There's a possibility of a time synchronization conflict between the Litmus Edge and the Virtual Machine (VM).

# Solution

To resolve this, ensure that both the VM's time settings are accurate and synchronized with an NTP (Network Time Protocol) source, and the Litmus Edge is properly configured to synchronize its time with the VM. 

The specific method for VM time synchronization depends on your hypervisor or VM setup.
