Many good ideas, but yours seemed the simplest and returned the correct values under all scenarios. Thanks!

For extra credit, is there a way to simplify the related code below? I'm stripping out the seconds.

m.SlotTime = RIGHT( "0" + ALLTRIM( slot_time( xx + show_from - 1 ) ), 5 )
m.DisplaySlotTime1 = Ttoc(Ctot(Transform(Dtos(Date()), '@R 9999-99-99') + 'T' + m.SlotTime), 2)
m.DisplaySlotTime2 = LEFT(m.DisplaySlotTime1,5) + ' ' + RIGHT(m.DisplaySlotTime1,2)
@ 2,2 SAY 'Date: ' + ALLTRIM( DTOC( disp_date ) ) + SPACE(10) + 'Time: ' + m.DisplaySlotTime2 COLOR ( nedit_color )
