Origin uses a 12 hour offset from the Astronomical Julian Day Number as 0 (January 1, 4713 BCE 12:00 AM). No assumptions are made about time zones or any time shifting scheme (such as Daylight Savings). For example, 11 June 1998 at 21:23:01 has an Origin Julian Day Number of 2450975.890984.
Matlab represents dates with 3 variable types: Date Strings, Date Vectors, and Date Serial Numbers. Serial Number dates are based on January 1, 0000
