> This operation is pretty slow:
> {code:java}
>   // Converts Date to TimestampTZ.
>   public static TimestampTZ convert(Date date, ZoneId defaultTimeZone) {
>     return parse(date.toString(), defaultTimeZone);
>   }
> {code}
> To convert from Date to TimestampTZ, it creates a string, then parses it.  Should be able to just look at the epoch time and do the conversion without all the string manipulation/parsing.
