How to change the time of a scheduled post
Open the scheduled Buzz on the Calendar, press the line that says when it goes out, pick a new day and time, and press Move it.
To keep the same time on another day, drag the Buzz to that day instead.
A scheduled Buzz can change until 2 minutes before it goes out. After that it's locked.
Change the day or time
1. Open Calendar in the menu, or press l.
2. Press the scheduled Buzz to open it in the panel on the right.
3. Press the line that says when it goes out.
4. Pick a day and a time at least 2 minutes from now, and press Move it.
To move it to another day at the same time, drag it there in any view. A day that can take it lights up, and anywhere else it springs back. On a touch screen, hold it still for a moment first.
Note: When the account's day is already full, or another post sits at that moment, the Buzz stays where it was and a message says why.
Change the words
Edit the words in the panel and press Save changes, or ⌘↵. Undo changes puts them back, and nothing changes on the platform until you save.
A thread, or a Buzz with its own text per platform, can't be edited in the panel. Move it back to drafts, change it in the composer and schedule it again.
If the change doesn't go through
If a platform won't take the change, the Buzz stays scheduled exactly as before and a message says so. Inside the last 2 minutes nothing about it can change.
Questions
Can I change the time of day by dragging?
No. Dragging moves a Buzz to another day at the same time. To change the time, open it and press the line that says when it goes out.
Which time zone is the new time in?
The Calendar shows times on your device's clock, and the line under its title names the zone. The Schedule popover uses the social set's own clock.
