MacOS:
- Go to Settings
- Date & Time
- Check the box “Set date and time automatically:”

If the Mac is managed by an organization, these options may be greyed out.
In that case, if the time is still incorrect, the user should contact their IT department.
Windows:
- Go to Settings (Windows + I)
- Time & language
- If there is a toggle for “Set time automatically”, set that to “On”.
- If not, try the ‘Sync Now” button in “Additional settings”.
If the computer is managed by the user’s org, some of these options may be greyed out; and if they are still incorrect, the user should contact their IT department.
