jpayne@69 19 * \brief C API: Universal Time Scale
jpayne@69 20 *
jpayne@69 21 * There are quite a few different conventions for binary datetime, depending on different
jpayne@69 22 * platforms and protocols. Some of these have severe drawbacks. For example, people using
jpayne@69 23 * Unix time (seconds since Jan 1, 1970) think that they are safe until near the year 2038.
jpayne@69 24 * But cases can and do arise where arithmetic manipulations causes serious problems. Consider
jpayne@69 25 * the computation of the average of two datetimes, for example: if one calculates them with
jpayne@69 26 * <code>averageTime = (time1 + time2)/2</code>, there will be overflow even with dates
jpayne@69 27 * around the present. Moreover, even if these problems don't occur, there is the issue of
jpayne@69 28 * conversion back and forth between different systems.
jpayne@69 29 *
jpayne@69 30 * <p>
jpayne@69 31 * Binary datetimes differ in a number of ways: the datatype, the unit,
jpayne@69 32 * and the epoch (origin). We'll refer to these as time scales. For example:

jpayne@69 165 * <p>
jpayne@69 166 * These functions implement a universal time scale which can be used as a 'pivot',
jpayne@69 167 * and provide conversion functions to and from all other major time scales.
jpayne@69 168 * This datetimes to be converted to the pivot time, safely manipulated,
jpayne@69 169 * and converted back to any other datetime time scale.
jpayne@69 170 *
jpayne@69 171 *<p>
jpayne@69 172 * So what to use for this pivot? Java time has plenty of range, but cannot represent
jpayne@69 173 * .NET <code>System.DateTime</code> values without severe loss of precision. ICU4C time addresses this by using a
jpayne@69 174 * <code>double</code> that is otherwise equivalent to the Java time. However, there are disadvantages
jpayne@69 175 * with <code>doubles</code>. They provide for much more graceful degradation in arithmetic operations.
jpayne@69 176 * But they only have 53 bits of accuracy, which means that they will lose precision when
jpayne@69 177 * converting back and forth to ticks. What would really be nice would be a
jpayne@69 178 * <code>long double</code> (80 bits -- 64 bit mantissa), but that is not supported on most systems.
jpayne@69 179 *
jpayne@69 180 *<p>
jpayne@69 181 * The Unix extended time uses a structure with two components: time in seconds and a
jpayne@69 182 * fractional field (microseconds). However, this is clumsy, slow, and
jpayne@69 183 * prone to error (you always have to keep track of overflow and underflow in the
jpayne@69 184 * fractional field). <code>BigDecimal</code> would allow for arbitrary precision and arbitrary range,
jpayne@69 185 * but we do not want to use this as the normal type, because it is slow and does not
jpayne@69 186 * have a fixed size.
jpayne@69 187 *
jpayne@69 188 *<p>
jpayne@69 189 * Because of these issues, we ended up concluding that the .NET framework's
jpayne@69 190 * <code>System.DateTime</code> would be the best pivot. However, we use the full range
jpayne@69 191 * allowed by the datatype, allowing for datetimes back to 29,000 BC and up to 29,000 AD.
jpayne@69 192 * This time scale is very fine grained, does not lose precision, and covers a range that
jpayne@69 193 * will meet almost all requirements. It will not handle the range that Java times do,
jpayne@69 194 * but frankly, being able to handle dates before 29,000 BC or after 29,000 AD is of very limited interest.
