We could definitely do this by using the timeStamp property on DataValue and let the user specify a "since" date in the export GUI. But the user is already specifying which months to export data for, typically only the last month so I am not sure how much we would save on the file size...

I was suggesting times when only few datavalues were changed in a given
period. Say for the last year's data, we changed only a few values and
the last month's data was not exported earlier. I would then need to
export 13 month's of data, whereas we can just export those diff
datavalues (changes from last year and this month's data)



Sure.

I think Lars by saying "sure" means it is possible using dataValue timeStamp field. If you modified some data for last year (don't know why? or this is allowed to do so after data have been reported?) in this month timeStamp will be the date of change ocured. So we need functionality which allows selecting certain date periods, like from this to that and so on. 
mesh4x proposed by Knut seems quite valuable tool, need time to look at.
