Export to Excel

Hi I am having an issue with the excel export for the Gantt Chart.
The dates in the excel seem to be in this format in the excel: 1430222400000
The export seemed to be working fine earlier, and the dates were in the same format as the JSON string. Could you please let me know if this is a known issue?

The JSON string for this start date is “start_date”:“04-28-2015 08:00:00” but it is rendered as 1430222400000 in the excel.


Can you share a demo or a snippet where ithe issue can be reconstructed?
