nanosOfDay

nanosOfDay returns the number of nanoseconds that have elapsed since the top of the day (midnight) for the specified date-time.

Syntax

nanosOfDay(dateTime, timeZone, localTime)
nanosOfDay(dateTime, localTime)
nanosOfDay(lotalTime)

Parameter	Type	Description
instant	Instant	The date-time from which to return the number of nanoseconds.
timeZone	ZoneId	The time zone.
dateTime	ZonedDateTime	The date-time from which to return the number of nanoseconds.
localTime	boolean	Set this parameter to `false` if you need Deephaven to account for daylight savings time. If `false`, returns the number of nanoseconds from the start of the day. However, on days when daylight savings time events occur, results may be different from what is expected based on the local time. For example, on DST change days, 9:30 AM may be earlier or later in the day based on whether the daylight savings time adjustment is forward or backward. On non-DST days, the result is the same as if `localTime` is `false`. If `true`, returns the number of nanoseconds from the start of the day according to the local time. In this case, `9:30` will always return the same value.

The specified date-time converted into nanoseconds. Null input values will return NULL_LONG.

datetime = parseInstant("2022-03-01T12:34:56 ET")

nanos = nanosOfDay(datetime, timeZone("ET"), false)
