 The following changes were made compared to the vanilla Google code:
   * the Time Zone Database may optionally be compiled into the library (just add a PEERDIR() to contrib/libs/cctz/tzdata subdirectory in your code);
   * some minor cleanups to avoid clang warnings;
-  * the tests were modified to work with library/cpp/testing/unittest.
