fix bug for this:
assume this was created :"2014/02/27 [15:15:43^15:16:27] [15:16:27^15:16:37] [15:16:37"
when you start idea at 2014/02/28 10:10:00 it will be:
"2014/02/27 [15:15:43^15:16:27] [15:16:27^15:16:37] [15:16:37^10:10:00]"
"2014/02/28 [10:10:00"

fixed to

"2014/02/27 [15:15:43^15:16:27] [15:16:27^15:16:37] [15:16:37^15:16:37]"
"2014/02/28 [10:10:00"
