problem is :

i run it on strategy tester , as you see the reading time is 2 hour less than the stored in write.

and if remove the "7200" in the first highlighted line time wll be the current time as below picture:

in real time chart as below:

also in strategy tester as below:

2-) the csv file :

3th column is time : ( is look blank )

problem solved: in first highlighted line :

(TimeToString(TIME_WRITE_BUY[wr] , TIME_DATE|TIME_SECONDS))
