I'm trying to retrieve the issues created last week using the following JQL clause
created >= startOfWeek(-1w) AND created <= endOfWeek(-1w)
However, it still returns issues created on Sunday two weeks ago, so it is effectively considering weeks going from SUN to SAT.
The system configuration has the option "Use ISO8601 standard in Date Picker" enabled, but this does not affect the StartOfWeek/EndofWeek functions.
May this issue be due to the fact default language is set to English US?
