How about the Julian Day as used by astronomers? http://en.wikipedia.org/wiki/Julian_day Julian day is used in the Julian date (JD) system of time measurement for scientific use by the astronomy community, presenting the interval of time in days and fractions of a day since January 1, 4713 BC Greenwich noon. Julian date is recommended for astronomical use by the International Astronomical Union.
Almost 2.5 million Julian days have elapsed since the initial epoch. JDN 2,400,000 was November 16, 1858. JD 2,500,000.0 will occur on August 31, 2132 at noon UT. (Often .leading 2.4 million is assumed and the low order 5 digits is used.) Time is expressed as a fraction of a day. 0.1 day = 2.4 hours, 0.01 = 14.4 minutes. 0.001 = 1.44 minutes, 0.00001 = 0.864 seconds. x.000 is Noon UT 1200Z Modified Julian Date subtracts 0.5 so x.000 is Midnight UT 0000Z.
