Node.js fs.utimesSync() Method Last Updated : 08 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The fs.utimesSync() method is used to synchronously 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.utimesSync( path, atime, mtime ) Parameters: This method accepts three 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. Below examples illustrate the fs.utimesSync() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // fs.utimesSync() method // Import the filesystem module const fs = require('fs'); console.log("Details before changing time:"); // Get the stats object of the file prevStats = fs.statSync("example_file.txt"); // Access the modified and access time of the file console.log("Modification Time:", prevStats.mtime); console.log("Access Time:", prevStats.atime); // Get the current time to change the timestamps let changedModifiedTime = new Date(); let changedAccessTime = new Date(); // Use the utimesSync() function to assign // the new timestamps fs.utimesSync("example_file.txt", changedAccessTime, changedModifiedTime); // Get the stats object of the file console.log("\nDetails after changing time:"); // Get the stats object of the file changedStats = fs.statSync("example_file.txt"); // Access the changed modified and access time of the file console.log("Changed Modification Time:", changedStats.mtime); console.log("Changed Access Time:", changedStats.atime); Output: Details before changing time: Modification Time: 2015-12-20T19:42:00.000Z Access Time: 2020-05-25T15:02:04.809Z Details after changing time: Changed Modification Time: 2020-05-25T15:09:37.412Z Changed Access Time: 2020-05-25T15:09:37.412Z Example 2: javascript // Node.js program to demonstrates the // fs.utimesSync() method // Import the filesystem module const fs = require('fs'); console.log("Details before changing time:"); // Get the stats object of the file prevStats = fs.statSync("example_file.txt"); // Access the modified and access time of the file console.log("Modification Time:", prevStats.mtime); console.log("Access Time:", prevStats.atime); // Get the current time to change the timestamps let changedModifiedTime = new Date("December 21, 2015 01:12:00"); let changedAccessTime = new Date("December 23, 2015 01:15:00"); // Use the utimesSync() function to assign // the new timestamps fs.utimesSync("example_file.txt", changedAccessTime, changedModifiedTime); // Get the stats object of the file console.log("\nDetails after changing time:"); // Get the stats object of the file changedStats = fs.statSync("example_file.txt"); // Access the changed modified and access time of the file console.log("Changed Modification Time:", changedStats.mtime); console.log("Changed Access Time:", changedStats.atime); Output: Details before changing time: Modification Time: 2020-05-25T15:09:37.412Z Access Time: 2020-05-25T15:09:37.412Z Details after changing time: Changed Modification Time: 2015-12-20T19:42:00.000Z Changed Access Time: 2015-12-22T19:45:00.000Z Reference: https://nodejs.org/api/fs.html#fs_fs_utimessync_path_atime_mtime Comment More infoAdvertise with us sayantanm19 Follow Improve Article Tags : Web Technologies Node.js Node.js-fs-module Similar Reads Node JS fs.readFile() Method ​In Node.js, the fs.readFile() method is a fundamental tool for reading files asynchronously, allowing your application to remain responsive while accessing file data. This method is part of Node.js's File System (fs) module, which provides an API for interacting with the file system.Syntaxfs.readFi 3 min read Node.js fs.exists() Method The fs exists method in node is used to check if the input file or the directory exists or not. It is an inbuilt application programming interface of fs module which provides an API for interacting with the file system in a manner closely modeled around POSIX functions. Syntax:fs.exists( path, callb 2 min read Node fs.existsSync() Method In Node.js, the fs.existsSync() method checks if a file or folder exists at a given path. It's synchronous, meaning it pauses the program until it finds the result (either true if it exists, or false if it doesn't). Because it stops everything while it works, it’s best used for quick checks in small 3 min read Node fs.mkdir() Method The fs.mkdir() method in Node.js is used to create a directory asynchronously.Syntaxfs.mkdir(path, mode, callback)Parameters: This method accepts three parameters as mentioned above and described below: path: This parameter holds the path of the directory that has to be created.mode: This parameter 2 min read Node.js fs.truncate() Method The fs.truncate() method in node.js is used to change the size of the file i.e either increase or decrease the file size. This method changes the length of the file at the path by len bytes. If len represents a length shorter than the file's current length, the file is truncated to that length. If i 2 min read Node.js fs.renameSync() Method In Node.js, the fs.renameSync() method is part of the built-in File System (fs) module and is used to rename or move files and directories synchronously. This method is useful when you need to quickly change a file's name or move it to a different directory synchronously. It blocks the execution of 3 min read Node.js fs.rmdir() Method The fs.rmdir() method is used to delete a directory at the given path. It can also be used recursively to remove nested directories.Syntax: fs.rmdir( path, options, callback )Parameters: This method accepts three parameters as mentioned above and described below: path: It holds the path of the direc 3 min read Node.js fs.stat() Method The fs.stat() method is used to return information about the given file or directory. It returns an fs.Stat object which has several properties and methods to get details about the file or directory.
