Go语言中DateTime的用法介绍

// Common durations. There is no definition for units of Day or larger
// to avoid confusion across daylight savings time zone transitions.
//
// To count the number of units in a Duration, divide:
//  second := time.Second
//  fmt.Print(int64(second/time.Millisecond)) // prints 1000
//
// To convert an integer number of units to a Duration, multiply:
//  seconds := 10
//  fmt.Print(time.Duration(seconds)*time.Second) // prints 10s
//<br data-filtered="filtered">
