const RFC3339 = "2006-01-02T15:04:05.999999999-07:00"

RFC3339 There is an edge case where there is no timezone set and that makes the format function return dates like 2019-09-03T20:48:57.073Z. We are using this RFC3339 custom format to always get an offset.

Functions

func AddDaysToStrDate

func AddDaysToStrDate(date string, days int) (string, error)

AddDaysToStrDate will add days to string date

func ConvertToModel

func ConvertToModel(ts time.Time, dateModel interface{})

ConvertToModel will fill dateModel based on passed time

func DateFromEpoch

func DateFromEpoch(t int64) time.Time

DateFromEpoch returns a time.Time from an epoch value in milliseconds

func DateRange

func DateRange(ref time.Time, timeunit int64) (int64, int64)

DateRange will return the beginning and end of a date range for a given time unit. if the timeunit is -1 it will return epoch zero

func DateRangePrevious

func DateRangePrevious(ref int64, timeunit int64) (int64, int64)

DateRangePrevious will previous time date for the previous range from timeunit

func EndofDay

func EndofDay(tv int64) int64

EndofDay returns the end of the day (midnight) for a given epoch time

func EpochMinuteApart

func EpochMinuteApart(epoch1, epoch2 int64) bool

EpochMinuteApart returns true if both epochs are less than or equal to one minute apart

func EpochNow

func EpochNow() int64

EpochNow will return the current time in epoch (in UTC) with millisecond precision

func GetSignalDate

func GetSignalDate(timeUnit int32, refDate time.Time) string

GetSignalDate returns a metric date in short form for a time unit from the ref date

func GetSignalTime

func GetSignalTime(timeUnit int32, refDate time.Time) time.Time

GetSignalTime returns a metric date for a time unit from the ref date This will be changed from -30 to -29 because of the next example Lets say I want to take 1 day from "yesterday at the end" lets say "2017-02-26 23:59:59.9999" that will result in "2017-02-25 23:59:59.9999" and after truncate "2017-02-25 00:00:00" so it is actually taken 2 days

func GetTimeUnitString

func GetTimeUnitString(timeUnit int32) string

GetTimeUnitString will return the timeunit as a string

func ISODate

func ISODate() string

ISODate returns a RFC 3339 formatted string for the current date time

func ISODateFromTime

func ISODateFromTime(t time.Time) string

func ISODateOffsetToTime(date string) (time.Time, error)

ISODateOffsetToTime returns a RFC 3339 formatted string as a timestamp

func ISODateToEpoch

func ISODateToEpoch(date string) (int64, error)

ISODateToEpoch returns an epoch date or 0 if invalid or empty

func ISODateToTime

func ISODateToTime(date string) (time.Time, error)

ISODateToTime returns a RFC 3339 formatted string as a timestamp

func ShortDate

func ShortDate(date string) string

ShortDate returns a DATE (no time) formatted string from RFC 3339 formatted string

func TimeFromDate

func TimeFromDate(date Date) time.Time

TimeFromDate returns a time.Time for a date

func TimeToEpoch

func TimeToEpoch(tv time.Time) int64

func ToMilliSec

func ToMilliSec(date time.Time) int64

ToMilliSec Convert time to milliseconds int64

func ToTimeRange

func ToTimeRange(tv time.Time, days int) (int64, int64)
