If you look in the welcome window, there should be a link to get to our sample code. In the Sample Code there is a folder called Graphics and inside that folder is a folder named AnchorPoints. This sample is basically a clock hand example that will cover what you want.

After that you look at that we can have a discussion on what anchor points are and how to use them.

By default, objects anchor at the centre.  This is known as obj.anchorX = 0.5 and obj.anchorY = 0.5.  The range is from 0 (left aligned) and 1 (right aligned) in X and 0 (top aligned) and 1 (bottom aligned) in Y.

This will explain it for you - https://docs.coronalabs.com/guide/graphics/transform-anchor.html#anchors

Thanks what I needed was x center aligned and y bottom aligned. Have another 2 questions about same app. Does corona support option to add button to set my clock app as live wallpaper and/or widget? Can slider widget be used to change background pictures?

Corona cannot be used to make live wallpaper or widget apps.

Thank you all for your answers was very helpful. Found that changing image can be done using sprite sheet and slider widget.
