Method Detail

truncate

public static ZonedDateTime truncate(ZonedDateTime time,
                                     ChronoUnit unit,
                                     int stepRate,
                                     DayOfWeek firstDayOfWeek)

Truncates the given time for the given chrono unit. The method ZonedDateTime.truncatedTo(java.time.temporal.TemporalUnit) is not sufficient as it only works for small units (hours, minutes, seconds). It does not work for any unit that has a variable duration (a month can be 28, 30, or 31 days long). We also want to be able to support a "step rate" (e.g. "truncate to minutes, to 5 minutes, to 15 minutes").

Parameters:

time - the time to truncate

unit - the chrono unit on which the truncation will be based

stepRate - the step rate (1, 5, 15, ....)

firstDayOfWeek - the first day of the week, needed for truncating weeks

Returns:

the truncated time

truncate

public static LocalTime truncate(LocalTime time,
                                 ChronoUnit unit,
                                 int stepRate)

Truncates the given time for the given chrono unit. The method ZonedDateTime.truncatedTo(java.time.temporal.TemporalUnit) is not sufficient as it only works for small units (hours, minutes, seconds). It does not work for any unit that has a variable duration (a month can be 28, 30, or 31 days long). We also want to be able to support a "step rate" (e.g. "truncate to minutes, to 5 minutes, to 15 minutes").

Parameters:

time - the time to truncate

unit - the chrono unit on which the truncation will be based

stepRate - the step rate (1, 5, 15, ....)

Returns:

the truncated time
