       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

       The _<_u_t_i_m_e_._h_> header shall declare the uuttiimmbbuuff structure, which shall
       include the following members:


           time_t    actime    Access time.
           time_t    modtime   Modification time.

       The times shall be measured in seconds since the Epoch.

       The _<_u_t_i_m_e_._h_> header shall define the ttiimmee__tt type as described in
       _<_s_y_s_/_t_y_p_e_s_._h_>.

       The following shall be declared as a function and may also be defined
       as a macro. A function prototype shall be provided.


           int utime(const char *, const struct utimbuf *);

AAPPPPLLIICCAATTIIOONN UUSSAAGGEE
       The _u_t_i_m_e() function only allows setting file timestamps to the nearest
       second.  Applications should use the _u_t_i_m_e_n_s_a_t() function instead. See
       _<_s_y_s_/_s_t_a_t_._h_>.

       The _<_u_t_i_m_e_._h_> header may be removed in a future version.
