# Date and Time Format MiVoice Office 400 CCS requires that the Short time format of the PC be 'HH:mm', which is 24 Hour format. If it is not set to 'HH:mm' the MiVoice Office 400 CCS Report system will not work properly. The Short date format can be set as required. However, due to a known bug with date and time formats in Windows 7, 8, and 10, MiVoice Office 400 CCS receives an incorrect time format until you actually CHANGE the date and time format. It does not matter which region the format is changed to, it can be any of those listed, and you can change it back to your preferred format right afterwards. What's important is that the change to the new format is APPLIED. You HAVE to do this step, but ONLY once. Afterwards, the correct 24 hour time format is always sent to MiVoice Office 400 CCS, even after a complete re-install. The date and time format is changed in 'Region and Language', which can be found in Control Panel > Clock, Language, and Region. IMPORTANT. You must also set the administrative short time format so that the MiVoice 400 CCS services use the 24h format. After setting the format for the user, follow these steps. First, click the Administrative tab. Then click the Copy settings button. On the dialog that opens, check the Welcome screen and system accounts check box. Click OK and Apply the changes.
