/**
 * Makes a timestamp which is periodically updated.
 * Initially shows time offsets in '<some_time> ago' manner. Later represents time depending on format,
 * wisely excluding unnecessary detais (i.e. 'year' if timestamp has been made this year, 'year' and 'month if in this month etc).
 * @class Q timestamp
 * @constructor
 * @param {array} $options Options for the tool
 *	@param {integer} [$options.time=time()] Unix timestamp (in seconds), defaults to value of time() call.
 *	@param {string} [$options.format] formatting string which makes specific timestamp representation.
 *	 Can contain placeholders supported by strftime() and also few special placeholders with specific functionality.
