ISSUE: 3150
|
|
TITLE: substring from timestamp - unexpected result
|
|
DESCRIPTION:
|
|
NOTES:
|
|
[26.01.2019] Note for 4.0.
|
|
Made more careful parsing for each token of timestamp because of time-with-timezone introduction.
|
|
[02.02.2019] Note for 4.0.
|
|
One need to EXPLICITLY add statement SET TIME ZONE <+HH:MM> at the beginning of test, otherwise
|
|
we will get eception because current_timestamp string will have length more than expected.
|
|
This is because DEFAULT time zone in FB 4.0 includes REGION NAME ('Moscow/Europe") instead of HH:MM shift.
