I changed the start date to my mint, saved in the edit page, but mint page has not reflected new time

I changed the start date of my mint from 9:00am to 7:00am today. It saved on the edit page, but hasn’t changed on the mint site. Does it take sometime to reflect the change in time or have I done something incorrectly? Thanks!

Gm - Is this still an issue? Did you sign a transaction after you made those changes?
