Method Details

parseDate

public static int parseDate(String value)

printDate

public static String printDate(int days)

convertToTimestampWithTimeZone

public static long convertToTimestampWithTimeZone(TimeZoneKey timeZoneKey,
 String timestampWithTimeZone)

Parse a string (optionally containing a zone) as a value of TIMESTAMP WITH TIME ZONE type. If the string doesn't specify a zone, it is interpreted in timeZoneKey zone.

For example: "2000-01-01 01:23:00" is parsed to TIMESTAMP WITH TIME ZONE 2000-01-01T01:23:00 <provided zone> and "2000-01-01 01:23:00 +01:23" is parsed to TIMESTAMP WITH TIME ZONE 2000-01-01T01:23:00.000+01:23.

Returns:

stack representation of TIMESTAMP WITH TIME ZONE type

parseLegacyTime

@Deprecated
public static long parseLegacyTime(TimeZoneKey timeZoneKey,
 String value)

Deprecated.

applicable in legacy timestamp semantics only

Parse a string (without a zone) as a value of TIME type, interpreted in timeZoneKey zone.

Returns:

stack representation of legacy TIME type

parseDayTimeInterval

public static long parseDayTimeInterval(String value,
 IntervalLiteral.IntervalField startField,
 Optional<IntervalLiteral.IntervalField> endField)

parseYearMonthInterval

public static long parseYearMonthInterval(String value,
 IntervalLiteral.IntervalField startField,
 Optional<IntervalLiteral.IntervalField> endField)
