I think you could add a specific CSS class to an element within the cell, and add the start date in an attribute (e.g. data-start-date="1414889795967"), then in a timer get all elements with the class (using getElementsByClassName or querySelectorAll; for now you'll have to use JSNI, or Elemental, or GQuery) and process their data-start-date="" attribute to compute the duration and set their content. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
