256986 Description of the Microsoft Windows Registry
This article describes how to determine the date format that is displayed to users when they log on to a computer.
A user can configure the date format using the Regional Settings tool in Control Panel.
You can apply a policy to a computer to control the date format that is displayed to the user (for example, MM/dd/yy or MM/dd/yyyy). The following registry key controls the date format:
Path: HKEY_CURRENT_USER\Control Panel\International Name: sShortDate Type: REG_SZ Default value for U.S. English: MM/dd/yy
The following example shows the different values you can use for this registry key, and how the date is displayed for a specified value:
Value ResultMM/dd/yy 03/08/98M/d/yy 3/8/98M/d/yyyy 3/8/1998MM/dd/yyyy 03/08/1998yy/MM/dd 98/03/08dd-MMM-yy 03-Mar-98
Through the use of policies in Windows NT 4.0, you can write a custom .adm file and incorporate it into the policy file. For additional information about policy files and custom .adm templates, please see the following article in the Microsoft Knowledge Base:
185589 Guide To Windows NT 4.0 Profiles and Policies (Part 4 of 6)
You can cut and paste the following information into a file and save it as a custom .adm file. After the .adm file is incorporated into the policy, you can configure the date format for users.
