I have a dropdown in my dashboard where I provide static label and value for 4 timezones as of now(UTC,ET,PST,CT) (Which maybe increased in future). Now, Upon choosing a timezone value from the dropdown, I will have to adjust _time in a search query(of a panel/input in my dashboard) like this--> "mysearch" | eval _time = _time (+ or - ) (x*60*60) | "rest of mysearch" (If I'm right, this approach is correct if the current user's timezone is set to UTC). But, the currently logged in user's timezone maybe any among UTC,ET,PST,CT. So, I will be overriding the timezone configured in the settings. How can I modify my search query for _time field dynamically taking into account the user's current timezone and considering daylight savings time for the above mentioned timezones as well ?
