Actually I throw away the seconds and hours and days and just keep the minutes. That way I see if there's something odd about the timing of record cutting - as I get 60 x axis values. Current customer data looks like this (chopping off all but the first 16 minutes):
PROD "MINUTE","SMF 30(2)","SMF 30(3)","SMF 70-79 00, 13573, 0, 240, 0, 01, 61, 1, 0, 0, 02, 37, 1, 0, 0, 03, 37, 0, 0, 0, 04, 21, 1, 0, 0, 05, 22, 1, 0, 0, 06, 30, 1, 0, 0, 07, 22, 1, 0, 0, 08, 14, 1, 0, 0, 09, 21, 1, 0, 0, 10, 20, 1, 0, 0, 11, 21, 1, 0, 0, 12, 11, 1, 0, 0, 13, 12, 1, 0, 0, 14, 15, 1, 0, 0, 15, 13588, 0, 240, 0, (Apologies if this unformats itself.)
