Why in my field data snapshots, the "time" column and the "time from start" column has the difference value. how this happen? and how to fix it.

Question

Why in my field data snapshots, the "time" column and the "time from start" column has the difference value. how this happen? and how to fix it. Because it's really confusing when i try to calibrate using the "time series field data", the simulated graph and field data graph has difference time value... 
 This is the field data 
 
 This is the simulated data 
 
 You notice that the time (hour) value is different. If those two graph becoming one. it would be like this...

How to fix this??? 
 Thank you,

Hi Tera, 
 The Time Form Start field in your field data set is a measure of the time that the field data was taken (as indicated by the date and time that is entered) compared to the Simulation Start Date and Start Time as defined in the calculation options of the Representative Scenario . 
 In other words, it's telling you how far your simulation time (if you run the representative scenario) is out with respect to your field data. To get these to match up, you should ensure that the Simulation Start Date and Start Time as defined in the calculation options of the Representative Scenario are set to something close to, but before, the date and times that the field data was acquired. You should then see the field data align correctly on the graphs. 
 Kind Regards, 
 Wayne.
