Well, there are a couple of ways to do this. You could
use the function LABEL_DATE to set up the time axis the
way you wanted to display the time. For example:

void = Label_Date(Date_Format='%D %M, %Y')
plot, time, vel, linestyle = 2, xtickformat='label_date'

Or, you can just use the calendar date formating codes
directly with the XTickFormat keyword:

plot, time, vel, linestyle = 2, xtickformat='(C(CDI,x,CMoA,x,CYI2))'

These formats obviously aren't correct with this data,
but I can't tell how the data should be formatted without
more information about what these Julian numbers mean.

Cheers,

David
