Hi,

What is the SessionRejectReason (Tag 373) when SendingTime/OriginalSendingTime format is incorrect?

For example,  
if inbound message contains 52=20151240-10:56:14.722, where valid format is “YYYYmmdd-HH:MM:SS.sss” and date (dd) contains value 40.

Is it [6 = Incorrect data format for value] or [10 = SendingTime Accuracy Problem] ?

Thanks.
