public AutoMedTime()

Create a new AutoMedTime that is a null value

Method Detail

dateValue

public java.util.Date dateValue()

toString

public java.lang.String toString()

Return a string representation of this AutoMedTime using ISO format. If the granularity is DAY or coarser then the format will be like {d '1970-01-01'} otherwise if will be like {ts '1970-01-10 12:00'}
