Go offers extensive support for times and durations;
here are some examples. | |
|  package main
|
| import (
"fmt"
"time"
)
|
| func main() {
p := fmt.Println
|
We’ll start by getting the current time. | now := time.Now()
p(now)
|
You can build a
time
struct by providing the
year, month, day, etc. Times are always associated
with a
Location
, i.e. time zone. | then := time.Date(
2009, 11, 17, 20, 34, 58, 651387237, time.UTC)
p(then)
|
You can extract the various components of the time
value as expected. | p(then.Year())
p(then.Month())
p(then.Day())
p(then.Hour())
p(then.Minute())
p(then.Second())
p(then.Nanosecond())
p(then.Location())
|
The Monday-Sunday
Weekday
is also available. | p(then.Weekday())
|
These methods compare two times, testing if the
first occurs before, after, or at the same time
as the second, respectively. | p(then.Before(now))
p(then.After(now))
p(then.Equal(now))
|
The
Sub
methods returns a
Duration
representing
the interval between two times. | diff := now.Sub(then)
p(diff)
|
We can compute the length of the duration in
various units. | p(diff.Hours())
p(diff.Minutes())
p(diff.Seconds())
p(diff.Nanoseconds())
|
You can use
Add
to advance a time by a given
duration, or with a
-
to move backwards by a
duration. | p(then.Add(diff))
p(then.Add(-diff))
}
