What's up with this?

This came in today from the City Clerk's office regarding the addition of a special City Commission meeting on March 4th - where they can take action! The City Clerk sent this out at 8:45 this morning but it's just the calendar. Today is March 4th! There is no agenda on the city's website for this March 4th special meeting. Note the disclaimer on the calendar - "Meetings are subject to change without notice."

Doesn't the Sunshine Law apply here? Shouldn't the minimum notice be 24 hrs. before the meeting?
