 ## Timers
 
 In addition to the full functionality of JS (as per ECMA5), the Ethereum Javascript Runtime Environment (JSRE) is augmented with various timers. It implements `setInterval`, `clearInterval`, `setTimeout`, `clearTimeout` which some users will be familiar with from browser windows. It also provides implementation for `admin.sleep(seconds)` and a block based timer, `admin.sleepBlocks(n)` which sleeps till the number of new blocks added is equal to or greater than `n`.
