JQL query for date time fields (e.g. created, updated) should show hidden 00:00 timestamp on search

Problem Definition

Currently when searching using date time fields (e.g. created, updated), if the timestamp is not specified, it will implicitly insert 00:00 to the query.

For example, with the below JQL,

created >= "2021-06-01"

it is implied in the system that it is actually

created >= "2021-06-01 00:00

This causes confusion to the user not aware that the time is implicitly set to 00:00.

Suggested Solution

If the time is not specified, the 00:00 should be added into the query string and be visible to the user after performing the search.
