public final class CivilTimeEncoderPorted from ZetaSQL CivilTimeEncoder Original code can be found at: https://github.com/google/zetasql/blob/master/java/com/google/zetasql/CivilTimeEncoder.java Encoder for TIME and DATETIME values, according to civil_time encoding.
The valid range and number of bits required by each date/time field is as the following:
| Field | Range | #Bits | 
|---|---|---|
| Year | [1, 9999] | 14 | 
| Month | [1, 12] | 4 | 
| Day | [1, 31] | 5 | 
| Hour | [0, 23] | 5 | 
| Minute | [0, 59] | 6 | 
| Second | [0, 59]* | 6 | 
| Micros | [0, 999999] | 20 | 
| Nanos | [0, 999999999] | 30 | 
* Leap second is not supported.
When encoding the TIME or DATETIME into a bit field, larger date/time field is on the more significant side.
