need to find start and end time of event e1

I have a table with 3 coulmne timestamp eventid active

timestamp	eventid	active
2020-02-01 22:44:23	E1	true
2020-02-01 22:45:23	E1	false
2020-02-01 22:46:23	E1	true
2020-02-01 22:47:23	E1	false
2020-02-01 22:44:23	E2	true
2020-02-01 22:45:23	E2	false
2020-02-01 22:46:23	E2	true

need to find start and end time of events here event e2 wont be considered as it is still active.
