Due Date set wrong date when I click OK

[ekomut]

Hi all,

Web I set Jira DueDate to "11.12.2019" by picker, I show same date in textbox. 
But When I click OK button, it sets "10.12.2019". Always 1 day ago.

This is my datetimes:
in the Look at Fields tab:

Time Format hh:mm

Day Format EEEE hh:mm

Complete Date/Time Format dd.MM.yy HH:mm

Day/Month/Year Format dd.MM.yy

Use ISO8601 standard in Date Picker Yes

in the General Configuration/Advanced Settings:

jira.date.picker.java.formatT d.MM.yy

jira.date.picker.javascript.format %d.%m.%y

jira.date.time.picker.java.format d.MM.yy H:mm

jira.date.time.picker.javascript.format %d.%m.%y %H:%M

might be the timezone issue, check if your jira/jvm/actual server times are the same
