Package civil implements types for civil time, a time-zone-independent representation of time that follows the rules of the proleptic Gregorian calendar with exactly 24-hour days, 60-minute hours, and 60-second minutes.
Because they lack location information, these types do not represent unique moments or intervals of time. Use time.Time for that purpose.

Types ¶
type Date ¶
type Date struct {
Year int // Year (e.g., 2014).
Month time.Month // Month of the year (January = 1, ...).
Day int // Day of the month, starting at 1.
}
A Date represents a date (year, month, day).
This type does not include location information, and therefore does not describe a unique 24-hour timespan.
func DateOf ¶
DateOf returns the Date in which a time occurs in that time's location.
func ParseDate ¶
ParseDate parses a string in RFC3339 full-date format and returns the date value it represents.
func (Date) AddDays ¶
AddDays returns the date that is n days in the future. n can also be negative to go into the past.
func (Date) AddMonths ¶
AddMonths returns the date that is n months in the future. n can also be negative to go into the past.
func (Date) AddYears ¶
AddYears returns the date that is n years in the future. n can also be negative to go into the past.
func (Date) After ¶
After reports whether d occurs after d2.
func (Date) Before ¶
Before reports whether d occurs before d2.
func (Date) Compare ¶
Compare compares d and d2. If d is before d2, it returns -1; if d is after d2, it returns +1; otherwise it returns 0.
func (Date) DaysSince ¶
DaysSince returns the signed number of days between the date and s, not including the end day. This is the inverse operation to AddDays.
func (Date) In ¶
In returns the time corresponding to time 00:00:00 of the date in the location.
In is always consistent with time.Date, even when time.Date returns a time on a different day. For example, if loc is America/Indiana/Vincennes, then both
time.Date(1955, time.May, 1, 0, 0, 0, 0, loc)
and
civil.Date{Year: 1955, Month: time.May, Day: 1}.In(loc)
return 23:00:00 on April 30, 1955.
In panics if loc is nil.
func (Date) IsValid ¶
IsValid reports whether the date is valid.
func (Date) IsZero ¶
IsZero reports whether date fields are set to their default value.
func (Date) MarshalText ¶
MarshalText implements the encoding.TextMarshaler interface. The output is the result of d.String().
func (Date) String ¶
String returns the date in RFC3339 full-date format.
func (*Date) UnmarshalText ¶
UnmarshalText implements the encoding.TextUnmarshaler interface. The date is expected to be a string in a format accepted by ParseDate.
func (Date) Weekday ¶
Weekday returns the day of the week for the date.
type DateTime ¶
A DateTime represents a date and time.
This type does not include location information, and therefore does not describe a unique moment in time.
func DateTimeOf ¶
DateTimeOf returns the DateTime in which a time occurs in that time's location.
func ParseDateTime ¶
ParseDateTime parses a string and returns the DateTime it represents. ParseDateTime accepts a variant of the RFC3339 date-time format that omits the time offset but includes an optional fractional time, as described in ParseTime. Informally, the accepted format is
YYYY-MM-DDTHH:MM:SS[.FFFFFFFFF]
where the 'T' may be a lower-case 't'.
func (DateTime) After ¶
After reports whether dt occurs after dt2.
func (DateTime) Before ¶
Before reports whether dt occurs before dt2.
func (DateTime) Compare ¶
Compare compares dt and dt2. If dt is before dt2, it returns -1; if dt is after dt2, it returns +1; otherwise it returns 0.
func (DateTime) In ¶
In returns the time corresponding to the DateTime in the given location.
If the time is missing or ambigous at the location, In returns the same result as time.Date. For example, if loc is America/Indiana/Vincennes, then both
time.Date(1955, time.May, 1, 0, 30, 0, 0, loc)
and
civil.DateTime{
civil.Date{Year: 1955, Month: time.May, Day: 1}},
civil.Time{Minute: 30}}.In(loc)
return 23:30:00 on April 30, 1955.
In panics if loc is nil.
func (DateTime) IsValid ¶
IsValid reports whether the datetime is valid.
func (DateTime) IsZero ¶
IsZero reports whether datetime fields are set to their default value.
func (DateTime) MarshalText ¶
MarshalText implements the encoding.TextMarshaler interface. The output is the result of dt.String().
func (DateTime) String ¶
String returns the date in the format described in ParseDate.
func (*DateTime) UnmarshalText ¶
UnmarshalText implements the encoding.TextUnmarshaler interface. The datetime is expected to be a string in a format accepted by ParseDateTime
type Time ¶
type Time struct {
Hour int // The hour of the day in 24-hour format; range [0-23]
Minute int // The minute of the hour; range [0-59]
Second int // The second of the minute; range [0-59]
Nanosecond int // The nanosecond of the second; range [0-999999999]
}
A Time represents a time with nanosecond precision.
This type does not include location information, and therefore does not describe a unique moment in time.
This type exists to represent the TIME type in storage-based APIs like BigQuery. Most operations on Times are unlikely to be meaningful. Prefer the DateTime type.
func ParseTime ¶
ParseTime parses a string and returns the time value it represents. ParseTime accepts an extended form of the RFC3339 partial-time format. After the HH:MM:SS part of the string, an optional fractional part may appear, consisting of a decimal point followed by one to nine decimal digits. (RFC3339 admits only one digit after the decimal point).
func TimeOf ¶
TimeOf returns the Time representing the time of day in which a time occurs in that time's location. It ignores the date.
func (Time) After ¶
After reports whether t occurs after t2.
func (Time) Before ¶
Before reports whether t occurs before t2.
func (Time) Compare ¶
Compare compares t and t2. If t is before t2, it returns -1; if t is after t2, it returns +1; otherwise it returns 0.
func (Time) IsValid ¶
IsValid reports whether the time is valid.
func (Time) IsZero ¶
IsZero reports whether time fields are set to their default value.
func (Time) MarshalText ¶
MarshalText implements the encoding.TextMarshaler interface. The output is the result of t.String().
func (Time) String ¶
String returns the date in the format described in ParseTime. If Nanoseconds is zero, no fractional part will be generated. Otherwise, the result will end with a fractional part consisting of a decimal point and nine digits.
func (*Time) UnmarshalText ¶
UnmarshalText implements the encoding.TextUnmarshaler interface. The time is expected to be a string in a format accepted by ParseTime.
