Update StartTime and EndTime of Calendar Event for all users and group members

[Dierk Polzin]

I need to update the start time and end time of campus wide event.

I can change the start and end time for one user at a time.. using

gam calendar vp...@college.edu update event id 2j5bkk8b3ai69lstart "2020-09-22T09:00:00-07:00"

gam calendar vp...@college.edu update event id 2j5bkk8b3ai69lupq end "2020-09-22T12:00:00-07:00"

But I am not seeing how to change it for each group that has been added. 

I don't really want to have to change the start and end time for each group member, there are hundreds.

Thanks

Seems like this might work..

gam calendar college.edu_s...@group.calendar.google.com update event id 2j5bkk8b3ai69lupqo start "2020-09-22T09:00:00-07:00" end "2020-09-22T12:00:00-07:00" notifyattendees     Calendar: college.edu_s...@group.calendar.google.com, Update 1 Event     Calendar: colleage.edu_...@group.calendar.google.com, Event: 2j5bkk8b3ai69lupqo, Updated
