This is more likely to stop people from replying. Everybody here is a volunteer, if your problem is that urgent, then get your credit card out and go to rentacoder.com. Firstly, try not to use ArrayList, use List instead. It is type safe and more efficient. Look it up in the documentation for further details. Something like:

		List timeList = new List();
		DateTime startTime = new DateTime(1, 1, 1, 9, 0, 0);
		DateTime endTime = new DateTime(1, 1, 1, 18, 0, 0);

		while (startTime <= endTime)
		{
			timeList.Add(startTime);
			startTime.AddMinutes(15);
		}

would work.

What will you do with it? Depending on what you plan to do, you may not actually need to store all that in memory. Here's an enumerator from my TimeRanger[^] article:

    public static System.Collections.Generic.IEnumerable<System.DateTime>
    MinuteEnumerator
    (
        System.DateTime StartPoint
    ,
        System.DateTime EndPoint
    ,
        ushort          SteppingFactor
    )
    {
        System.DateTime current = PIEBALD.Lib.LibTim.DateTruncate 
        ( 
            StartPoint 
        , 
            PIEBALD.Lib.LibTim.TimeGranularity.Minute 
        ) ;
        
        if ( StartPoint <= EndPoint )
        {
            if ( current < StartPoint )
            {
                current = current.AddMinutes ( 1 ) ;
            }

            while ( current <= EndPoint )
            {
                yield return ( current ) ;
                
                current = current.AddMinutes ( SteppingFactor ) ;
            }
        }
        else
        {
            while ( current >= EndPoint )
            {
                yield return ( current ) ;
                
                current = current.AddMinutes ( SteppingFactor\*-1 ) ;
            }
        }
                    
        yield break ;
    }

Or you could use this to load a List if you really want to store the information.
