Class CivilTimeEncoder (3.10.2) 

public final class CivilTimeEncoder

Ported 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:

Range and bits for date/time fields
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.
