Returns a copy of this datetime minus the specified number of minutes.
The calculation will subtract a duration equivalent to the number of minutes expressed in milliseconds.
The following three lines are identical in effect:
DateTime subtracted = dt.minusMinutes(6); DateTime subtracted = dt.minus(Period.minutes(6)); DateTime subtracted = dt.withFieldAdded(DurationFieldType.minutes(), -6);
This datetime instance is immutable and unaffected by this method call.
@param minutes the amount of minutes to subtract, may be negative
@return the new datetime minus the increased minutes
