PARAMETERS: According to the C2x charter, I reordered the parameters 'size' and 'buf' from previously existing date_to_str() definitions. C2x charter: > 15. Application Programming Interfaces (APIs) should be > self-documenting when possible. In particular, the order of > parameters in function declarations should be arranged such that > the size of an array appears before the array. The purpose is to > allow Variable-Length Array (VLA) notation to be used. This not > only makes the code's purpose clearer to human readers, but also > makes static analysis easier. Any new APIs added to the Standard > should take this into consideration. I used 'long' for the date parameter, as some uses of the function need to pass a negative value meaning "never". FUNCTION BODY: I didn't check '#ifdef HAVE_STRFTIME', which old definitions did, since strftime(3) is guaranteed by the C89 standard, and all of the conversion specifiers that we use are also specified by that standard, so we don't need any extensions at all.

shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
