How do I get the Unix epoch in seconds for a date without time?

2021-12-31T22:42:14

In Go, how do I get the Unix epoch in seconds for a date without time?

For example, if I want the Unix epoch seconds for the current time, I can use:

today := time.Now().Unix()

For instance, if the current date+time is 2021-12-31 11:56:01, I want to get the Unix epoch in seconds for 2021-12-31 00:00:00. Is there an easy way to do this, or do I have to convert to a string, manipulate the string, then parse the string?
