+ The full set of format codes supported varies across platforms,
+ because Python calls the platform C library's strftime() function,
+ and platform variations are common.  The documentation for Python's
+ time module lists the format codes that the C standard (1989 version)
+ requires, and those will work on all platforms with a standard C
+ implementation.  Note that the 1999 version of the C standard added
+ additional format codes.
+ 
+ The exact range of years for which strftime() works also varies
+ across platforms.  For example, Microsoft's implementation of
+ strftime() refuses to accept years before 1900, and Python inherits
+ this limitation.
