Method Details

create

public static <ATTR extends Attributes.Any> ToDBDateTimePageFromInt96<ATTR> create(@NotNull Class<?> nativeType)

setReferenceTimeZone

public static void setReferenceTimeZone(@NotNull String timeZone)

Allows overriding the time zone to be used when interpreting Int96 timestamp values. Default is UTC. Can be set globally with the parameter deephaven.parquet.referenceTimeZone. Valid values are time zone Strings which would be used in convertDateTime, such as NY.

Parameters:

timeZone -
