If you have an Android phone, you can change the clock on your lock screen. This is a great way to keep track of the time when you’re not at home or when you’re out of town. To do this, open the Settings app and select Clock. Under Clock, select Change Time. In the new window that pops up, enter the time you want to change and click OK. You’ll now see a new clock on your lock screen that matches the time you entered.
