Description

Currently, Spark SQL's date-time expressions and functions are ported on Java 8 time API but tests still use old time APIs. In particular, DateTimeTestUtils exposes functions that accept only TimeZone instances. This is inconvenient, and CPU consuming because need to convert TimeZone instances to ZoneId instances via strings (zone ids). The tickets aims to replace TimeZone parameters of DateTimeTestUtils functions by ZoneId type.
