PivotTable and Charts do not support user's time zone

[Flaurite]

Environment

• Platform version: 6.10
• Client type: Web

Description of the bug or enhancement

• Minimal reproducible example

1. Create entity with dateTime property.
2. Create some instances with dateTime values (26.06.2019 10:00, 26.06.2019 11:00)
3. After that in the 'Settings' screens change time zone (AGT (GMT-03:00))

• Expected behavior
  In the browser screen in table cell we can see -> 26.06.2019 03:00 and 26.06.2019 04:00.
  So in the pivotTable we should see the same values.
• Actual behavior
  But if we open pivotTable we will see 26.06.2019 10:00 and 26.06.2019 11:00

In chart we can see the same behavior.
