Add returns the time t+d, using a configurable mode.

AddMicros adds the microsecond delta to the provided time value.

Decode reverses the three integers returned from Encode and produces an equal Duration to the original.

DecodeDuration returns a Duration without rounding nanos.

DiffMicros computes the microsecond difference between two time values.

FromBigInt converts a big.Int number of nanoseconds to a duration.

FromFloat64 converts a float64 number of seconds to a duration.

FromInt64 converts an int64 number of seconds to a duration.

MakeDuration returns a Duration rounded to the nearest microsecond.

Truncate returns a new duration obtained from the first argument by discarding the portions at finer resolution than that given by the second argument.

DaysPerMonth is the assumed amount of days in a month.

DaysPerYear is the number of days in a year.

MicrosPerMilli is the amount of microseconds in a millisecond.

MillisPerSec is the amount of seconds in a millisecond.

MonthsPerYear is the amount of months in the year.

SecsPerDay is the amount of seconds in a day.

SecsPerHour is the amount of seconds in an hour.

SecsPerMinute is the amount of seconds in a minute.

A Duration represents a length of time.
