millisOfDay

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

Syntax

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

Parameters

ParameterTypeDescription
instantInstant

The date-time from which to return the elapsed time.

timeZoneZoneId

The time zone.

dateTimeZonedDateTime

The date-time from which to return the elapsed time.

localTimeboolean

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

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

Examples

datetime = parseInstant("2023-09-09T12:34:56.123456 ET")

millis = millisOfDay(datetime, timeZone("ET"), false)

println millis
