Functions

func ParseDateTime

func ParseDateTime(str string, loc *time.Location) (t time.Time, err error)

ParseDateTime parses SQL DATE or DATETIME string in specified location.

Types

type Date

type Date struct {
	time.Time
}

Date is used to save and output YYYY-MM-DD format date string.

func DateFrom

func DateFrom(t time.Time) Date

DateFrom creates a new Time wrapping time.Time.

func DateNow

func DateNow() Date

DateNow creates current time.

func DateZero

func DateZero() Date

DateZero creates the zero value of Time.

func (Date) MarshalJSON

func (d Date) MarshalJSON() ([]byte, error)

MarshalJSON converts a Time struct to ISO8601 string.

func (*Date) Scan

func (d *Date) Scan(value interface{}) (err error)

Scan implements the Scanner interface. SQL NULL will be turned into time zero value.

func (Date) String

func (d Date) String() string

func (*Date) UnmarshalJSON

func (d *Date) UnmarshalJSON(data []byte) (err error)

UnmarshalJSON converts ISO8601 data time into a Time struct. Empty string and null will be turned into time.Time zero value.

func (Date) Value

func (d Date) Value() (driver.Value, error)

Value implements the driver Valuer interface. Zero value is turned into SQL NULL.

type Time

type Time struct {
	time.Time
}

Time is used to save and output ISO8601 date time with time zone set to UTC.

func TimeFrom

func TimeFrom(t time.Time) Time

TimeFrom creates a new Time wrapping time.Time.

func TimeNow

func TimeNow() Time

TimeNow creates current time.

func TimeZero

func TimeZero() Time

TimeZero creates the zero value of Time.

func (Time) MarshalJSON

func (t Time) MarshalJSON() ([]byte, error)

MarshalJSON converts a Time struct to ISO8601 string.

func (*Time) Scan

func (t *Time) Scan(value interface{}) (err error)

Scan implements the Scanner interface. SQL NULL will be turned into time zero value.

func (Time) StringCN

func (t Time) StringCN() string

StringCN produces the string representation in Chinese format with locale set to Asia/Shanghai.

func (Time) StringEN

func (t Time) StringEN() string

StringEN produces the string representation in English with locale set to UTC.

func (*Time) UnmarshalJSON

func (t *Time) UnmarshalJSON(data []byte) (err error)

UnmarshalJSON implements the json.Unmarshaler interface. The time is expected to be a quoted string in RFC 3339 format. Empty string and null will be turned into time.Time zero value.

func (Time) Value

func (t Time) Value() (driver.Value, error)

Value implements the driver Valuer interface. Zero value is turned into SQL NULL.
