Method Detail

timeInMsOrOneIfResultIsZero

public static long timeInMsOrOneIfResultIsZero(long time,
                                               TimeUnit timeUnit)

Convert time to milliseconds based on the given time unit. If conversion result is 0 and time was > 0, then 1 is returned.

Parameters:

time - The input time

timeUnit - The time unit to base the conversion on

Returns:

The millisecond representation of the input time

Throws:

NullPointerException - if time unit is null

timeInMsOrTimeIfNullUnit

public static long timeInMsOrTimeIfNullUnit(long time,
                                            TimeUnit timeUnit)

Convert time to milliseconds based on the given time unit. If time unit is null, then input time is treated as milliseconds.

Parameters:

time - The input time

timeUnit - The time unit to base the conversion on

Returns:

The millisecond representation of the time based on the unit, or the time itself if the unit is null

zeroOutMs

public static long zeroOutMs(long timestamp)

Cleans the milliseconds info from the timestamp

Parameters:

timestamp - The input timestamp

Returns:

The timestamp with the milliseconds field filled with zeros
