I answered a similar question on Stack Overflow. I wanted a timestamp in a specific format, that could be obtained from a function repeatedly. My implementation is different than the original posters, for very specific reasons. The goal is thus to create a simple timestamp structure and a function that can create it repeatedly without arguments.
  • In a conversion from string to timestamp, millisecond (MS) or microsecond (US) values are used as the seconds digits after the decimal point.For example to_timestamp('12:3', 'SS:MS') is not 3 milliseconds, but 300, because the conversion counts it as 12 + 0.3 seconds.

As mentioned above, the GPHDFS protocol converts Hive timestamp data type to bytea data type, which is actually an array of 12 bytes made of 2 parts: byte 7~byte 0: Time elapsed in the day in nanoseconds. byte 11~byte8: Julian date. Based on this information, a UDF could be created in Greenplum to convert the 12-byte timestamp data to Epoch date.
