+>>>>>>> f051a8e8452... * Bugs 15163 16496 fixed [doc]: getdate() page rewritten
* Translations added:
- (ru): `weekday`
* [#14488](https://bugzilla.scilab.org/14488): The `frameflag=9` and `strf=".9."` values of these `plot2d` options were no longer accepted. Their documentation was ambiguous.
* [#14718](https://bugzilla.scilab.org/14718): `user` is removed for a while but was still documented.
* [#14873](https://bugzilla.scilab.org/14873): `setfield` page: The output and the 6.0 history were documented only on the en_US version. The input was wrongly restricted to matrices, while any Scilab object is acceptable. The specific role of `setfield` for mlists was not really described nor illustrated. The example did not include any call to setfield.
+* [#15163](https://bugzilla.scilab.org/15163): `getdate` page: The time referential was obscure: a) UTC for Unix Time Convention vs Coordinated Universal Time. b) unclear influence of the time zone.
* [#15280](https://bugzilla.scilab.org/15280): `gsort` was unable to sort any hypermatrix along dimensions > "r"|"c".
* [#15839](https://bugzilla.scilab.org/15839): `gsort`: the only sparse possible input were real or complex vectors, and only with the `g` method.
* [#15842](https://bugzilla.scilab.org/15842): `unique` could not process 2D sparse matrices.
* [#16465](https://bugzilla.scilab.org/16465): Scinotes OpenRecent menu was not updated when it should.
* [#16473](https://bugzilla.scilab.org/16473): Deleting rows in a sparse squared the matrix with padding zeros (Scilab 6 regression).
* [#16474](https://bugzilla.scilab.org/16474): `imult(%z)` crashed Scilab.
+* [#16496](https://bugzilla.scilab.org/16496): The `getdate` page should be rewritten: a) `getdate("s")` does NOT take leap seconds into account. b) `D=getdate(X)` is vectorized, accepts fractional seconds and returns them in [0,1) in D(10) instead of milliseconds. Moreover, the time referential of the result was unclear (time zone, daylight saving offset).
* [#16517](https://bugzilla.scilab.org/16517): `getdate("s")` truncated the actual time to integer seconds. `getdate(u)(10)` returned fractional seconds instead of milliseconds as `getdate()`.
* [#16522](https://bugzilla.scilab.org/16522): `bitget(x,pos)` and `bitset(x,pos)` results could be wrong when `pos` is an encoded integer.
* [#16525](https://bugzilla.scilab.org/16525): `soundsec(t,freq)` has the trivial equivalence `0 : 1/freq : t*(1-%eps)` and should be removed.
-
### Bugs fixed in 6.1.0:
* [#2694](https://bugzilla.scilab.org/2694): `bitget` did not accept positive integers of types int8, int16 or int32.
* [#5824](https://bugzilla.scilab.org/5824): The `datafit` algorithm was not documented.

+ Nowadays, most of computers are automatically synchronized with the legal time

+ <emphasis role="bold">getdate("s")</emphasis> reads the computer's clock
+ and returns the corresponding POSIX timestamp. This corresponds to the number
+ of seconds elapsed since 1970-01-01 00:00:00 UTC, except that leap seconds
+ are not counted. Hence, if <literal>n = getdate("s")</literal> is run at an
+ exact round hour, <literal>modulo(n, 3600)</literal> will return 0 instead

+ </para>
+ <para>
+ <emphasis role="bold">getdate(timeStamps)</emphasis> returns the status of the
+ local computer's clock for the given POSIX time stamps, that may include fractional
+ seconds. If any, the computer's current Daylight Saving offset is never considered.
+ <literal>getdate(0)</literal> will return 1970-01-01 00:00:00
+ only if the clock is set for the time zone = 0. Otherwise, for instance for
+ Scilab users living in Bélem, Brazil, UTC-3, <literal>getdate(0)</literal> returns
+ 1969-12-31 21:00:00, actually corresponding to 1970-01-01 00:00:00 POSIX.
