Hi,

I have a list (a time series):

data={{00:00:30,x1},{00:01:00,x2},{00:01:30,x3},....}

at equally spaced time intervals (30 seconds). The length od data is
8100 (24 h)

DateListPlot[data] works fine but takes 28 sec, since
ListPlot[data[[All,2]]] does it in less than 0.1 sec....

Can you explain me why DateListPlot is so time consuming? Can we
improve it?

Best,

Arek
