自golang纳秒时间戳以来的时间(Time since golang nanosecond timestamp)

time.Time

Timetime.Unix(sec int64, nsec int64)nsec[0, 999999999]

time.Since(t Time)time.Duration

t := time.Unix(0, yourTimestamp)
elapsed := time.Since(t)

Duration.Hours()

fmt.Printf("Elapsed time: %.2f hours", elapsed.Hours())

Try it on the Go Playground.

Note:

Duration"72h3m0.5s"String()

fmt.Printf("Elapsed time: %s", elapsed)
