-.TH UTIME 2 2014-08-19 "Linux" "Linux Programmer's Manual"
-.SH NAME
-utime, utimes \- change file last access and modification times
-.SH SYNOPSIS
-.nf
-.B #include <sys/types.h>
-.br
-.B #include <utime.h>
-.sp
-.BI "int utime(const char *" filename ", const struct utimbuf *" times );
-.sp
-.B #include <sys/time.h>
-.sp
-.BI "int utimes(const char *" filename ", const struct timeval " times [2]);
-.fi
-.SH DESCRIPTION
-.B Note:
-modern applications may prefer to use the interfaces described in
-.BR utimensat (2).
-
-The
-.BR utime ()
-system call
-changes the access and modification times of the inode specified by
-.I filename
-to the
-.IR actime " and " modtime
-fields of
-.I times
-respectively.
-
-If
-.I times
-is NULL, then the access and modification times of the file are set
-to the current time.
-
-Changing timestamps is permitted when: either
-the process has appropriate privileges,
-or the effective user ID equals the user ID
-of the file, or
-.I times
-is NULL and the process has write permission for the file.
-
-The
-.I utimbuf
-structure is:
-
-.in +4n
-.nf
-struct utimbuf {
- time_t actime; /* access time */
- time_t modtime; /* modification time */
-};
-.fi
-.in
-
-The
-.BR utime ()
-system call
-allows specification of timestamps with a resolution of 1 second.
-
-The
-.BR utimes ()
-system call
-is similar, but the
-.I times
-argument refers to an array rather than a structure.
-The elements of this array are
-.I timeval
-structures, which allow a precision of 1 microsecond for specifying timestamps.
-The
-.I timeval
-structure is:
-
-.in +4n
-.nf
-struct timeval {
- long tv_sec; /* seconds */
- long tv_usec; /* microseconds */
-};
-.fi
-.in
-.PP
-.IR times [0]
-specifies the new access time, and
-.IR times [1]
-specifies the new modification time.
-If
-.I times
-is NULL, then analogously to
-.BR utime (),
-the access and modification times of the file are
-set to the current time.
-.SH RETURN VALUE
-On success, zero is returned.
-On error, \-1 is returned, and
-.I errno
-is set appropriately.
-.SH ERRORS
-.TP
-.B EACCES
-Search permission is denied for one of the directories in
-the path prefix of
-.I path
-(see also
-.BR path_resolution (7)).
-.TP
-.B EACCES
-.I times
-is NULL,
-the caller's effective user ID does not match the owner of the file,
-the caller does not have write access to the file,
-and the caller is not privileged
-(Linux: does not have either the
-.B CAP_DAC_OVERRIDE
-or the
-.B CAP_FOWNER
-capability).
-.TP
-.B ENOENT
-.I filename
-does not exist.
-.TP
-.B EPERM
-.I times
-is not NULL,
-the caller's effective UID does not match the owner of the file,
-and the caller is not privileged
-(Linux: does not have the
-.B CAP_FOWNER
-capability).
-.TP
-.B EROFS
-.I path
-resides on a read-only filesystem.
-.SH CONFORMING TO
-.BR utime ():
-SVr4, POSIX.1-2001.
-POSIX.1-2008 marks
-.BR utime ()
-as obsolete.
-.br
-.BR utimes ():
-4.3BSD, POSIX.1-2001.
-.SH NOTES
-Linux does not allow changing the timestamps on an immutable file,
-or setting the timestamps to something other than the current time
-on an append-only file.
-.\"
-.\" In libc4 and libc5,
-.\" .BR utimes ()
-.\" is just a wrapper for
-.\" .BR utime ()
-.\" and hence does not allow a subsecond resolution.
