I am using CMSSW_5_3_32 to analyze the “/DoubleMu/Run2011A-12Oct2013-v1/AOD” dataset (DoubleMu primary dataset in AOD format from RunA of 2011). I would like to extract the event recored time of each event, just like displayed in CERN Open Data Portal, e.g. “data recorded: 2011-Jun-25 00:14:59.597978 GMT”. Could you tell me how to do that? Thank you so much!
