- $Log: date.h,v $
- Revision 1.3 2002-09-28 06:58:45 arjen
- Bugfix: conversion of an empty string to a date or hour object
- now makes the values of such an object 0 (null) instead of giving
- a segmentation fault.
- The class UTC combines the date and hour classes. The most basic
- functions of the UTC class are now implemented.
- These include constructors and conversion to and from String objects.
- New functions: date::proper(), hour::proper() and UTC::proper().
- Return true if the object holds a proper clock time and/or calendar
- date; false if at least one value is out of range.
-
- Revision 1.2 2002/09/02 06:18:20 arjen
- Fixed some date and time conversion functions
-
- Revision 1.1 2002/07/25 08:01:26 arjen
- First checkin, AXE release 0.2
