please use something like the provided link to make discord use timestamps in relative time instead of providing timezone, it takes 2 seconds so that no one has to go and google w/e timezone they live in vs the timezone that you're posting about.
it would looke like this
"Hey we're releasing XYZ at <t:1771585200:s>"
Automatically convert times and dates to the Discord timestamp format to display times in everyone's local timezone.
