What is the default time interval for the API request /public/events?

Hi All,
In order to get eventlogs, we should use this api request:
First query without specifying the time: GET https://api.bitwarden.com/public/events
And we can specify the time interval with this formate:
Second query with start and end time: GET https://api.bitwarden.com/public/events?start=YYYY-MM-DDT00:00:00.00&end=YYYY-MM-DDT00:00:00.00

My question is: If I use the first query without specify the start and end time, what is the default start and end time will be used?, for example, get all events for last 5 minutes?

Regards
