ClientServerTimeService - small class to work with server-synched time on the client

I have many client operations that need to be time-synched with the server.

I started having code littered all over the place and decided to wrap it up into a neat little object.

Here is the first pass of this class (and some usage examples):

 /**   * Small class that will attempt to deliver the server time on the client.   * Pretty narrow scope, basically only usefull in my SuiteLets.  The SuiteLet   * adds a hidden text field that will have the server time set just before   * the response is returned.  Then on the client side when this class is instantiated   * it will read the server time from the hidden field and calculate the differential.   */  function ClientServerTimeService()  {      var _serverTime = DateUtils.CreateDateFromMilliseconds(          nlapiGetFieldValue(ClientServerTimeService.SRVR_TIME_FLD_ID));                var _serverLocalDifferential = _serverTime.getTime() - new Date().getTime();            /**       * Returns the calculated server time based on the server-set
