    Method
    Description
    static org.joda.time.DateTime
    fromBigqueryTimestampString(String timestampString)
    Returns the DateTime for a given human-readable string-formatted BigQuery timestamp.
    static String
    toBigqueryTimestamp(long timestamp, TimeUnit unit)
    Converts a time (in TimeUnits since the epoch) into a numeric string that BigQuery understands as a timestamp: the decimal number of seconds since the epoch, precise up to microseconds.
    static String
    toBigqueryTimestamp(org.joda.time.DateTime dateTime)
    Converts a DateTime into a numeric string that BigQuery understands as a timestamp: the decimal number of seconds since the epoch, precise up to microseconds.
    static String
    toBigqueryTimestampString(org.joda.time.DateTime dateTime)
    Returns the human-readable string version of the given DateTime, suitable for conversion within BigQuery from a string literal into a BigQuery timestamp type.
    static String
    toJobReferenceString(com.google.api.services.bigquery.model.JobReference jobRef)
    Returns the canonical string format for a JobReference object (the project ID and then job ID, delimited by a single colon) since JobReference.toString() is not customized to return it.

    • BIGQUERY_TIMESTAMP_FORMAT

      public static final org.joda.time.format.DateTimeFormatter BIGQUERY_TIMESTAMP_FORMAT
      A DateTimeFormatter that defines how to print DateTimes in a string format that BigQuery can interpret and how to parse the string formats that BigQuery emits into DateTimes.

      The general format definition is "YYYY-MM-DD HH:MM:SS.SSS[ ZZ]", where the fractional seconds portion can have 0-6 decimal places (although we restrict it to 0-3 here since Joda DateTime only supports up to millisecond precision) and the zone if not specified defaults to UTC.

      Although we expect a zone specification of "UTC" when parsing, we don't emit it when printing because in some cases BigQuery does not allow any time zone specification (instead it assumes UTC for whatever input you provide) for input timestamp strings (see b/16380363).

      public static String toBigqueryTimestamp(org.joda.time.DateTime dateTime)
      Converts a DateTime into a numeric string that BigQuery understands as a timestamp: the decimal number of seconds since the epoch, precise up to microseconds.

      Note that since DateTime only stores milliseconds, the last 3 digits will be zero.
