Method Detail

getMillisFromTicks

public static long getMillisFromTicks(long hi,
                      long lo)

Converts from two-word tick representation to milliseconds. Mainly useful in conjunction with COBOL date conversion.

convertDate

public static String convertDate(long stamp,
                 int format)

Converts the given timestamp into an ISO8601 date.

convertDate

public static String convertDate(long stamp,
                 int format,
                 String outputFormat)

Converts the given timestamp into a date string with the given format.

convertDate

public static String convertDate(long stamp,
                 int format,
                 String outputFormat,
                 boolean correctTimeZoneForGMT)

Converts the given timestamp into a date string with the given format. If correctTimeZoneForGMT is set, then the timestamp will be interpreted as being relative to GMT and not the local time zone.

formatDate

public static String formatDate(String date,
                String format)

Formats the given date as an ISO 8601 date. Delegates to formatDate(String, String, boolean), with the 'lenient' flag set to false.

Parameters:

date - The date to format as ISO 8601.

format - The date's input format.

formatDate

public static String formatDate(String date,
                String format,
                boolean lenient)

Formats the given date as an ISO 8601 date.

Parameters:

date - The date to format as ISO 8601.

format - The date's input format.

lenient - Whether or not to leniently parse the date.

formatDate

public static String formatDate(String date,
                String[] formats)

Formats the given date as an ISO 8601 date. Delegates to formatDate(String, String[], boolean), with the 'lenient' flag set to false.

Parameters:

date - The date to format as ISO 8601.

formats - The date's possible input formats.

formatDate

public static String formatDate(String date,
                String[] formats,
                boolean lenient)

Formats the given date as an ISO 8601 date.

Parameters:

date - The date to format as ISO 8601.

formats - The date's possible input formats.

lenient - Whether or not to leniently parse the date.

getTime

public static long getTime(String date,
           String format)

Converts a string date in the given format to a long timestamp (in Unix format: milliseconds since January 1, 1970).
