DateTime display ignores time zone of the operator
We have two consecutive user actions. In the first one user sets date and time to DateTimeCalc property (type DateTime), using the standart DateTime control. Ex. 21.06.2019 10:21, according to the clipboard property DateTimeCalc has value "20190621T072100.000 GMT". Said property is displayed later on a section of next user action. The user expects to see value of DateTimeCalc property he entered earlier, 21.06.2019 10:21, instead he sees DateTimeCalc = 21.06.2019 7:21.
How can we fix it and show the user the time value relevant for his timezone?
