Redstone Clock (Expanded Redstone)

The Redstone Clock is a block added by Expanded Redstone. It sends a redstone signal at specified intervals. It allows for specifying how long the clock is on and off. The time it spends outputting a signal can be changed by right-clicking the block while sneaking, while the time it spends off can be changed by right-clicking the block while not sneaking. Powering the clock with a Redstone Repeater will pause its timer. On and off time are set independently from one another and can individually be any of the following times. They both default to 1 second (20 ticks).
 * 0.1 second (2 ticks)

 * 5 minutes (6,000 ticks)
 * 10 minutes (12,000 ticks)
