1. Open images folder.
2. Add new folder with your own name. Name your folder without any spaces.
3. Create your own pictures and locate them in. You have to use same pictures extension for all images.
4. Ensure that your pictures have names according to this name convention: clock face: bkg, second hand: second, minute hand: minute, hour hand: hour.
5. Create your clock code in creator above (with different clock images).
6. Copy generated code to your project then replace this parameter with name of your folder: clock: 'your-folder-name'.

There are two options to get time from. Default is to get time from end-user computer (local).
If you assume, your user device (PC, mobile etc.) time is correct, you can rely on that.
To be 100% sure, that all users will see the same time - you can use PHP Time option.
To work properly, you have to put your clock code in PHP file on working PHP server.

PHP time will work only if PHP server is working well, you have to have PHP at 5.1 version at least.
If PHP time is not working, sClock will automatically get time from end user local time.
You can easily check if your PHP time is working well using PHP debug option.

This option could be useful, when you wanted to check if time from PHP is working well.
Just check this option, to receive alerts from JavaScript informing that PHP time is working well or not.
This option should be used only when debugging and it should be always disabled on production systems.
