17 * \brief C API: Universal Time Scale
21 * Unix time (seconds since Jan 1, 1970) think that they are safe until near the year 2038.
30 * and the epoch (origin). We'll refer to these as time scales. For example:
33 * <caption>Table 1: Binary Time Scales</caption>
112 * All of the epochs start at 00:00 am (the earliest possible time on the day in question),
164 * These functions implement a universal time scale which can be used as a 'pivot',
165 * and provide conversion functions to and from all other major time scales.
166 * This datetimes to be converted to the pivot time, safely manipulated,
167 * and converted back to any other datetime time scale.
170 * So what to use for this pivot? Java time has plenty of range, but cannot represent
171 * .NET <code>System.DateTime</code> values without severe loss of precision. ICU4C time addresses this by using a
172 * <code>double</code> that is otherwise equivalent to the Java time. However, there are disadvantages
179 * The Unix extended time uses a structure with two components: time in seconds and a
190 * This time scale is very fine grained, does not lose precision, and covers a range that
197 * <code>UDateTimeScale</code> values are used to specify the time scale used for
198 * conversion into or out if the universal time scale.
277 * Similar to Unix time (linear value from 1970) and struct timeval
