ActionTime

Currently, we use Joda Time for the ActionTime field. To use other format for time, developers may look into the following classes.

• DateBase: specifies the pattern of time.
• DayIntConverter: converts a time in the pattern described in DateBase to an integer.
• TimeUnits: units used for age calculation in cohort analysis. Day is used by default.
• TimeUtils: utility functions to process time and age.
