convert string into time in VB.net

I have 3 dropdown lists. each preloaded with hour, minute and [PM/AM] respectively.
I have code that concatenates these into a string value like "3:00 AM"

I'm having trouble converting that into a dateTime format. Instead i would get todays date with 1:00 AM. Any ideas?

ERF.EventStartTime = Convert.ToDateTime(ESTHourDropDownList.SelectedValue + ":" + ESTMinsDropDownList.SelectedValue + " " + ESTampmDropDownList.SelectedValue)
