Custom time until status revert's or changes

The current 1, 3, 4hrs presets for setting a status time is great but there are times where I want to go something in between like a 1.5hrs or 5/6hrs but I can't due to them not being an option

On each status have an option at the end (or start) that says "For ....." or "Until...." and clicking on that give a clock and/or calendar pop up that lets you pick a date and/or time that your status stays active until

As other tickets have said, It would also be good to have a timer next to your status (that only you can see) that shows when the current status expires
