If you want to return statistics from a particular period of time, you can specify the start date from which to include statistics using MinTimestamp.

You must specify MinTimestamp in epoch seconds (seconds since 1 January, 1970). For example, to return all statistics starting from Friday 21 December 10:28:18 2012, set MinTimestamp to 1356085698.
