Set global default

Default timezone is UTC, language locale is English, start day of the week is Monday and weekend days of the week are Saturday and Sunday.

Set single default values

go

carbon.SetLayout(carbon.DateTimeLayout)
carbon.SetTimezone(carbon.UTC)
carbon.SetLocale("en")
carbon.SetWeekStartsAt(carbon.Monday)
carbon.SetWeekendDays([]carbon.Weekday{carbon.Saturday, carbon.Sunday,})

Set multiple default values

go

carbon.SetDefault(carbon.Default{
  Layout: carbon.DateTimeLayout,
  Timezone: carbon.UTC,
  Locale: "en",
  WeekStartsAt: carbon.Monday,
  WeekendDays: []carbon.Weekday{carbon.Saturday, carbon.Sunday,},
})

Reset default values

go

carbon.ResetDefault()

This is particularly useful in testing to ensure that changes in one test don't affect others.
