In case of Linux, for time functions we have a _r versions Ex: localtime has localtime_r, but in Windows I am unable to find some such functions. Are the Windows time functions inherently thread-safe?

With Microsoft Visual Studio you have a choice of c-runtimes to use: typically they were:
The multithreaded libraries are thread safe. The single threaded library was last seen in MSVC 2005 and has been dropped from MSVC 2008.
The dll runtime (msvcrt.dll) just has to be thread safe – As the implementation is in a dll and therefore shared between multiple other modules in the process, all of which could be using worker threads, It has to be threadsafe as there would be no sane way to design an application to use it otherwise.
