• If the VM has a clock skew (incorrect time)

  sudo service ntp stop
  sudo ntpd -gq
  sudo service ntp start
  

• If you need to test time and/or date dependent elements, you can change it in the vagrant machine so you don’t have to wait. To remove the syncing and set your own time:

  sudo systemctl disable ntp
  timedatectl set-ntp 0
  sudo date -s "<year>-<month>-<day> <hour>:<minute>:<seconds>
  

  To check the date, helpful to make sure the date and time you set has stuck:

  date
  

  To sync back with the current time:

  sudo systemctl enable ntp
  timedatectl set-ntp 1
