![]() For the nanosecond part of the epoch offset, the regular nanosecond component ( instant.nanosecond) can be used.Ĭomponents of Duration values are truncated within their component groups as follows: Component GroupĮach set of 4 quarters is counted as 1 year each set of 12 months is counted as 1 year.Įach year is counted as 4 quarters each set of 3 months is counted as 1 quarter.Įach year is counted as 12 months each_quarter_ is counted as 3 months.Įach set of 60 minutes is counted as 1 hour each set of 3600 seconds is counted as 1 hour.Įach hour is counted as 60 minutes each set of 60 seconds is counted as 1 minute.Įach hour is counted as 3600 seconds each minute is counted as 60 seconds.Įach set of 1000 milliseconds is counted as 1 second.Įach millisecond is counted as 1000 microseconds.Įach microsecond is counted as 1000 nanoseconds. The expression datetime().epochMillis returns the equivalent value of the timestamp() function.Ħ. Cypher does not support leap seconds UTC-SLS (UTC with Smoothed Leap Seconds) is used to manage the difference in time between UTC and TAI (International Atomic Time).ĥ. Note: very few database systems like PostgreSQL, SQL Server 2008 etc., offers a unique type to store timestamp with time zone. For dates from December 29, this could be the next year, and for dates until January 3 this could be the previous year, depending on how week 1 begins.Ĥ. The first week of any year is the week that contains the first Thursday of the year, and thus always contains January 4.ģ. years AD/CE start at year 1, and the year before that (year 1 BC/BCE) is 0, while year 2 BCE is -1 etc.Ģ. This is in accordance with the Gregorian calendar i.e. The number of seconds between T00:00:00+0000 and the instant. This provides a set of generic Offset From UTC time zones in the range. Positive for instants after and negative for instants before T00:00:00+0000 A default UTC time zone backend is provided which is always guaranteed to be available. The number of milliseconds between T00:00:00+0000 and the instant. The day-of-the-week component (alias for instant.dayOfWeek).ĭepending on how the time zone was specified, this is either a time zone name or an offset from UTC in the format ±HHMM The day-of-the-week component (the first day of the week is Monday). The year that the week-of-year component belongs to. For more information, see the rules for using the Year component The year component represents the astronomical year number of the instant. Components of temporal instant values and where they are supported Component Deprecations, additions and compatibilityĬomponents of temporal instant values can be accessed as properties.
