Jarrison Time requires Windows Region settings configured a certain way for date formatting.


Regional settings changed on a user profile are not automatically applied to Windows services, which can cause incorrect format issues. dates, language, etc.). This occurs because Windows uses separate settings for User accounts and System accounts (services, welcome screen), and updating only the user profile does not update system settings.
The solution is to copy current settings to other logins.
- Open Control Panel → Region
- Go to the Administrative tab
- Click Copy settings…
- Tick: Welcome screen and system accounts and New user accounts
- Click OK, then Apply
- Restart the PC
