What time zone to choose for jira?

Hi all.
Live in Kiev, the question is: how to choose the correct time zone ?

JIRA profile time zone: +0200 Kiev

Confluence profile timezone: +0200 Athens, Istanbul
Where Kiev ?

Confluence calendar
Timezone: +0300 Europe / Kiev
d488d26af8d14ba8bf114646e5cd8421.png

Already +0300

What could be the problem ?
