I think it's a manifestation of the magnitude bug in the default toolkit 
(fltk?). The problem is that fltk can't plot intervals that have a short 
span compared to the magnitude of the endpoints. Since you don't seem to 
care about the actual date,  resetting the beginning to midnight works 
around that:

plot(ser_date-datenum("00:00:00"),T ,'color','k' )
