millisOfDay

millisOfDay returns the number of milliseconds since midnight for a specified date-time.

Syntax

millisOfDay(instant, timeZone, localTime)
millisOfDay(dateTime, localTime)
millisOfDay(localTime)

Parameter	Type	Description
instant	Instant	The date-time from which to return the elapsed time.
timeZone	ZoneId	The time zone.
dateTime	ZonedDateTime	The date-time from which to return the elapsed time.
localTime	boolean	Set this parameter to `false` if you need Deephaven to account for daylight savings time. If `false`, returns the number of milliseconds 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 milliseconds from the start of the day according to the local time. In this case, `9:30` will always return the same value.

Returns the number of milliseconds since midnight for the date-time, or NULL_INT if dt is None.
