Ignoring holidays/weekends: always 9:30AM or (0930) EST. Same with EDT: 9:30AM.
The key here is that the timezone info includes the daylight/standard designation. Or, in the ISO format -4:00 or -5:00 from UTC.
I think you meant to put ET (Eastern Time), which is still 9:30AM, but without a date associated with that time, there's no way to convert that to UTC or other timezones that don't have the same daylight saving time schedule.
