Are your posts not going out when they're supposed to, or is this little clock at the top right showing the wrong time? Well, you might just need to change the time zone. Go to "Workspace Preferences". Now, you're going to go down to "Company Settings" and see where it says "Time Zone". Make sure it says the correct time zone for where you are located. And please note that when you create a subuser, like a different team member, they can actually set their own time zone within their own user preferences. So please instruct them of that if they're experiencing this and they complain of this to you.
If you want to change your date format for your local area, you can also do that here as well. And be sure to check here if you have daylight savings time observed in your particular state or country.
