Equal reports whether s and r represent the same time intervals, ignoring the locations of the times.

Before reports whether s ends before t.

Follows reports whether s begins after or at the end of r.

New creates a new span with the given start instant and duration.

Precedes reports whether s ends before or at the start of r.

After reports whether s begins after t.

ContainsTime reports whether t is within s.

Duration returns the length of time represented by s.

Borders reports whether s and r are contiguous time intervals.

Contains reports whether r is entirely within s.

Intersection returns both a span corresponding to the non-zero overlap of s and r and a bool indicating whether such an overlap existed. If s and r do

Encompass returns the minimum span that fully contains both r and s.

Gap returns a span corresponding to the period between s and r. If s and r have a non-zero overlap, a zero span is returned.

End returns the time instant at the end of s.

Offset returns s with its start time offset by d. It is equivalent to Newspan(s.Start().Add(d), s.Duration()).

OffsetDate returns s with its start time offset by the given years, months, and days. It is equivalent to Newspan(s.Start().AddDate(years, months, day

Start returns the time instant at the start of s.

IsZero reports whether s represents the zero-length span starting and ending on January 1, year 1, 00:00:00 UTC.

Overlaps reports whether s and r intersect for a non-zero duration.

tmax returns the later of two time instants.

tmin returns the earlier of two time instants.
