When must one set his mind to fast during the month of Ramadan?

One must observe the intention for fasting before the fajr. However, if he did not do so, his fasting is invalid.
Allah said ( interpretation of the meaning ) :
{ And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the sunset.}
