I have a series of time-stamps taken from a pump station where I need to evaluate the operating intervals in minutes.
The stamps run over day ends, month and even years so I am looking for a simple way to count time from a fixed date .. even a recent date such as '2008 01 01 00 00.00' would be fine. data example: 2008 12 01 00 46 16 2008 12 01 01 46 19 2008 12 01 03 49 52 2008 12 01 04 49 56 2008 12 01 09 05 33 I have been doing this the hard way with lots of 'intervention' but probably somebody has already solved this elegantly and ideas would be appreciated.
