[Dx4win] JTDX adif import "time_on" vs "time_off"

[ly2ij at qrz.lt]

Hi,

I use JTDX for 6m FT8 and import its adif file to DX4WIN and then upload contacts to LoTW from DX4WIN .
Some people complained why we don't haw LoTW match. 

JTDX keeps both "QSO_on" (time_on) time when first answered to this CALL and "QSO_completed" (time_off) time when QSO was finished.
Time difference between these two can be significant with propagation on and off rapidly o 6m.

It looks to me that DX4WIN imports "time_on" field as "QSO_time" from ADIF file, see line below - DX4WIN logged 07:45 this stations.

I always used "time_off" for logging.
Any ideas? "Search and replace" can be used once, but..
