How Do I Change My Account's Time Format?
Whether you prefer using a 12-hour format or a 24-hour format, you can easily change it from your Workspace Details. To find this menu, go to your User Settings at the top-right corner, click Edit Profile, and then head to Workspace Details from the left-side navigation menu.
Once here, you will see your Time Format settings where you can choose between 24-hour (military time) or 12-hour.
