Description

Usage

Sys.setFileTime(path, time)

Arguments

path

A length-one character vector specifying the path to a file or directory.

time

A date-time of class "POSIXct" or an object which can be coerced to one. Fractions of a second are ignored.

Logical, invisibly. An indication if the operation succeeded.

Details

This attempts sets the file time to the value specified.

On a Unix-alike it uses the system call utimes if that is available, otherwise utimes. On a POSIX file system it sets both the last-access and modification times.

On Windows it uses the system call SetFileTime to set the ‘last write time’. Some Windows file systems only record the time at a resolution of two seconds.
