EA Modification

I am looking to modify this EA that I had someone code a while back.

The EA basically measures the range during 2 periods of time (R1=Range 1 and R2=Range 2) which can be set by the user. Currently, I have to manually change the dates for the R1Start, R1End, R2Start, R2End times everyday which has become a hassle. The R1Start, R1End and R2Start are always on the same day but the R2End time is always the following day.

How can the coding be changed so I do not have to change the date for the above parameters?

The coding is below. I have also attached the EA file.

Thanks alot,

CFII
