Method Detail

toPackedLong

public static long toPackedLong(ExtendedDateTime extendedDateTime,
                                org.joda.time.DateTimeZone tz)

Encode a DateTime to a packed long converting to specific timezone

Parameters:

extendedDateTime - dateTime with nanos that need to be encoded.

tz - timezone used for converting to localDateTime

Returns:

a packed long.

fromPackedLong

public static ExtendedDateTime fromPackedLong(long packed,
                                              org.joda.time.DateTimeZone tz)

Read datetime from packed Long which contains all parts of a datetime namely, year, month, day and hour, min and sec, millisec. The original representation does not indicate any timezone information In Timestamp type, it should be interpreted as UTC while in DateType it is interpreted as local timezone

Parameters:

packed - long value that packs date / time parts

tz - timezone to interpret datetime parts

Returns:

decoded DateTime using provided timezone

createExtendedDateTime

public static ExtendedDateTime createExtendedDateTime(org.joda.time.DateTimeZone tz,
                                                      int year,
                                                      int month,
                                                      int day,
                                                      int hour,
                                                      int minute,
                                                      int second,
                                                      int microsec)

writeDateTimeFully

                                      ExtendedDateTime extendeddateTime,
                                      org.joda.time.DateTimeZone tz)

Encode DateTime as packed long converting into specified timezone All timezone conversion should be done beforehand

Parameters:

cdo - encoding output

extendeddateTime - value to encode

tz - timezone used to converting local time

writeDateTimeProto
