u can use DateTime.Now.Hour.ToString() and  see if it is less than 12
or u can use DateTime.TimeOfDay Property

it's always after midnight. if it's before midnight it's yesterday.

ok, now for a serious answer. the hour should be 1 for 1 am instead of 13 for 1 pm

A little more info on this.

I have a phone log file which is updated will call information throughout the day.

Add midnight, I want to take all call information older than 30 days and append it to another table.

The append part is already done....I just want to make sure the timing is correct.

This only needs to fire ONCE a day....between midnight and 1 AM, for example.

You could use a separate time for this portion and just have it run once every 24 hours.

Otherwise you would want to do something like

// Initialize a default LastRun.  This will always run the first time.
// because the initialization will not be today.
DateTime LastRun = New DateTime();

in your timer function.

// Check if it's currently between midnight and 1 am.
if( DateTime.Now.Hour > 0 && DateTime.Now.Hour < 1  )
{
   // Make sure this has not run already today.
   if( DateTime.Now.Date > LastRun )
   {
      LastRun = Datetime.Now;
      // run the append process.
   }
}
