The purpose of this library was to replace our dependence on Unix epoch time,
|
||
|
|
which, being limited to a range of about 1970 to 2030, is inadequate for our
|
||
|
|
purposes (we have data as old as 1870). This date library effectively handles
|
||
|
|
dates from A.D. 1000 to infinity, and would probably work all the way back to 0
|
||
|
|
(ignoring, of course, the switch-over to the Gregorian calendar). The useful
|
||
|
|
features of Unix epoch time (ease of date difference calculation and date
|
||
|
|
comparison, strict ordering) are preserved, and elements such as
|
||
|
|
human-legibility are added. The library handles fractional seconds and some
|
||
|
|
date/time manipulations used for the Global Positioning Satellite system.
