Time and date
time package provides functionality for handling time and date.
Major types in the package:
time.Timerepresents time and date values
time.Durationrepresents difference between two
time.Timevalues in nanoseconds
time.Millisecondetc. are constants of
time.Durationthat are easier to use than nanoseconds
Get current time and date
now := time.Now()
Construct a time and date at a given moment in time
t := time.Date(year int, month Month, day, hour, min, sec, nsec int, loc *Location) Time
loc must be provided and represents time zone. Use
time.UTC variable for UTC time zone.
Compare two times for equality
areEqual := t1.Equal(t2)
Add duration to time
newTime := now.Add(5 * time.Second + time.Millisecond * 100)
Time values are immutable.
Add returns a new value.
Substract duration from time
newTime := now.Add(-6 * time.Second)
To substract 6 seconds we add -6 seconds.
Add years, months, days to time
Adding a duration is for durations smaller than 24 hours.
To advance time by calendar years, months or days, use:
years := 2 months := 3 days := 13 t2 := t.AddDate(years, months, days)
Convert time to Unix representation of time
For interoperability with existing code you often need to use Unix time, which is defined as number of seconds since January 1, 1970 UTC.
unixTime := t.Unix()
Get year, month and day from time
year, month, day := t.Day()
