The
fs.utimes() method is used to asynchronously change the modification and access timestamps of a file. The timestamps can be specified using a number, string, or Date object. An error would be thrown if the timestamp cannot be converted to a proper number, or is NaN, Infinity or -Infinity.
Syntax:
fs.utimes( path, atime, mtime, callback )
Parameters: This method accepts four parameters as mentioned above and described below:
- path: It is a string that denotes the path of the file whose timestamps have to be changed.
- atime: It is number, string or Date object that denotes the new access timestamp to be set.
- mtime: It is number, string or Date object that denotes the new modification timestamp to be set.
- callback: It is a function that would be called when the method is executed.
- err: It is an error that would be thrown if the method fails.
