Sys.setFileTime:

Description

Uses system calls to set the times on a file or directory.

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 (prior to R 3.4.0).

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 utime. 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.
