.BR utimensat ()

update the timestamps of a file with nanosecond precision.

This contrasts with the historical

.BR utime (2)

and
|
|
|
|
.BR utimes (2),
|

|
|
which permit only second and microsecond precision, respectively,
|
|
|
|
when setting file timestamps.

That form is more consistent, logical, precise, and internationally
recognizable than the other variants.
Also, some wording has been altered as well.

Various pages: Improve formatting in ATTRIBUTES
Make the formatting more consistent inside the tables in the
ATTRIBUTES sections. Make the source code more uniform; in
particular, eliminate the use of custom tweaks using
'lbwNN'/'lwNN' and .br macros. In addition, ensure that
hyphenation and text justification do not occur inside the tables.
This is a script-driven edit:

Blank lines shouldn't generally appear in *roff source (other
than in code examples), since they create large vertical
spaces between text blocks.

On Linux, timestamps cannot be changed for a file marked immutable,

|
|
|
|
Several bugs afflict
|
|
|
|
.BR utimensat ()
|
|
|
|
and
|
|
|
|
.BR futimens ()
|
|
|
|
on kernels before 2.6.26.
|
2010-01-16 16:48:00 +00:00
|
|
|
These bugs are either nonconformances with the POSIX.1 draft specification
|
2008-07-16 08:42:14 +00:00
|
|
|
or inconsistencies with historical Linux behavior.
|

|
|
|
.IP * 3
|
2008-07-16 08:42:14 +00:00
|
|
|
POSIX.1 specifies that if one of the
|
|
|
|
.I tv_nsec
|
|
|
|
fields has the value
|
|
|
|
.B UTIME_NOW
|
|
|
|
or
|
|
|
|
.BR UTIME_OMIT ,
|
|
|
|
then the value of the corresponding
|
|
|
|
.I tv_sec
|
|
|
|
field should be ignored.
|
|
|
|
Instead, the value of the
|
|
|
|
.I tv_sec
|
|
|
|
field is required to be 0 (or the error
|
|
|
|
.B EINVAL
|
|
|
|
results).
|
|
|
|
.IP *
|
|
|
|
Various bugs mean that for the purposes of permission checking,
|
|
|
|
the case where both
|
|
|
|
.I tv_nsec
|
|
|
|
fields are set to
|
|
|
|
.BR UTIME_NOW
|
|
|
|
isn't always treated the same as specifying
|
|
|
|
.I times
|
|
|
|
as NULL,
|
|
|
|
and the case where one
|
|
|
|
.I tv_nsec
|
|
|
|
value is
|
|
|
|
.B UTIME_NOW
|
|
|
|
and the other is
|
|
|
|
.B UTIME_OMIT
|
|
|
|
isn't treated the same as specifying
|
|
|
|
.I times
|
2008-09-29 10:42:09 +00:00
|
|
|
as a pointer to an array of structures containing arbitrary time values.
|
2008-07-16 08:42:14 +00:00
|
|
|
As a result, in some cases:
|
|
|
|
a) file timestamps can be updated by a process that shouldn't have
|
|
|
|
permission to perform updates;
|
|
|
|
b) file timestamps can't be updated by a process that should have
|
|
|
|
permission to perform updates; and
|
|
|
|
c) the wrong
|
|
|
|
.I errno
|
|
