I haven't seen a way to do this from within XO. However, you can gather the details using
xeon the command line --for i in `xe snapshot-list | grep uuid | awk '{print$5}'`; do export j=$(xe snapshot-param-get uuid=$i param-name=children); k=$(xe snapshot-param-get uuid=$i param-name=snapshot-time); echo "VM UUID: $j - Snapshot UUID: $i - Creation Time: $k"; doneThis doesn't sort the results, so you will need to do that in Excel or your favorite text editor.
@Danp adding | sort -t: -k4 to your command will sort it by date.
-t:set fields separator to:-k4sort by 4th field
