type Time struct {
// contains filtered or unexported fields
}
Time is a wrapper for time.Time for additional features.
func ConvertZone ¶
ConvertZone converts time in string <strTime> from <fromZone> to <toZone>. The parameter <fromZone> is unnecessary, it is current time zone in default.
func New ¶
func New(param ...interface{}) *Time
New creates and returns a Time object with given parameter. The optional parameter can be type of: time.Time/*time.Time, string or integer.
func NewFromStr ¶
NewFromStr creates and returns a Time object with given string. Note that it returns nil if there's error occurs.
func NewFromStrFormat ¶
NewFromStrFormat creates and returns a Time object with given string and custom format like: Y-m-d H:i:s. Note that it returns nil if there's error occurs.
func NewFromStrLayout ¶
NewFromStrLayout creates and returns a Time object with given string and stdlib layout like: 2006-01-02 15:04:05. Note that it returns nil if there's error occurs.
func NewFromTime ¶
NewFromTime creates and returns a Time object with given time.Time object.
func NewFromTimeStamp ¶
NewFromTimeStamp creates and returns a Time object with given timestamp, which can be in seconds to nanoseconds. Eg: 1600443866 and 1600443866199266000 are both considered as valid timestamp number.
func ParseTimeFromContent ¶
ParseTimeFromContent retrieves time information for content string, it then parses and returns it as *Time object. It returns the first time information if there're more than one time string in the content. It only retrieves and parses the time information with given <format> if it's passed.
func StrToTime ¶
StrToTime converts string to *Time object. It also supports timestamp string. The parameter <format> is unnecessary, which specifies the format for converting like "Y-m-d H:i:s". If <format> is given, it acts as same as function StrToTimeFormat. If <format> is not given, it converts string as a "standard" datetime string. Note that, it fails and returns error if there's no date string in <str>.
func StrToTimeFormat ¶
StrToTimeFormat parses string <str> to *Time object with given format <format>. The parameter <format> is like "Y-m-d H:i:s".

func (*Time) IsLeapYear ¶
IsLeapYear checks whether the time is leap year.
func (*Time) IsZero ¶ added in v1.15.7

func (*Time) NoValidation ¶ added in v1.16.0
func (t *Time) NoValidation()
NoValidation marks this struct object will not be validated by package gvalid.
func (*Time) Round ¶
Round returns the result of rounding t to the nearest multiple of d (since the zero time). The rounding behavior for halfway values is to round up. If d <= 0, Round returns t stripped of any monotonic clock reading but otherwise unchanged.
Round operates on the time as an absolute duration since the zero time; it does not operate on the presentation form of the time. Thus, Round(Hour) may return a time with a non-zero minute, depending on the time's Location.

StartOfYear clones and returns a new time which is the first day of the year and its time is set to 00:00:00.
func (*Time) Sub ¶ added in v1.10.1
Sub returns the duration t-u. If the result exceeds the maximum (or minimum) value that can be stored in a Duration, the maximum (or minimum) duration will be returned. To compute t-d for a duration d, use t.Add(-d).

func (*Time) Truncate ¶
Truncate returns the result of rounding t down to a multiple of d (since the zero time). If d <= 0, Truncate returns t stripped of any monotonic clock reading but otherwise unchanged.
Truncate operates on the time as an absolute duration since the zero time; it does not operate on the presentation form of the time. Thus, Truncate(Hour) may return a time with a non-zero minute, depending on the time's Location.
func (*Time) UnmarshalJSON ¶ added in v1.9.7
UnmarshalJSON implements the interface UnmarshalJSON for json.Unmarshal.
func (*Time) UnmarshalText ¶ added in v1.15.2
