Defect #30288
Updated by Marius BĂLTEANU over 5 years ago
The following problems may occur when grouping by date (TimeWithZone).
# group count is not displayed
# The displayed created_on and group name date are different
Precondition:
# Use PostgreSQL or MySQL
# Database time zone is JST (It is not just JST)
# User's time zone is unset (User.current.time_zone is nil)

In environments where the above conditions apply, the test of "IssuesControllerTest#test_index_grouped_by_created_on [test/functional/issues_controller_test.rb:365]" fails.
