Wromg time in Spark 2.6.3


I use OpenFire 3.7.1 and Spark 2.6.3 (both on Windows platform). In Russia where I work the switching from/to winter/summer time was canceled.
I have noticed that in Spark chat window the time is wrong - it differs (less) from system time by 1 hour.
If anybody knows what is wrong? How to solve this problem?
