Knowing the exact build date of your software or website is crucial for various reasons, from debugging and troubleshooting to tracking progress and ensuring compliance. It allows developers to pinpoint the specific version of code deployed at a particular time, facilitating faster issue resolution. For end-users, it offers transparency and builds trust, demonstrating a commitment to continuous improvement and maintenance. This article will delve into different methods for displaying the build date, providing actionable insights and best practices for implementation.
Using Build Tools for Automated Date Injection
Modern build tools like Webpack, Gulp, and Grunt offer powerful features for automating the process of injecting the build date into your application. These tools can be configured to read the timestamp from your version control system or generate a new timestamp during the build process and insert it directly into your HTML, JavaScript, or other source files. This ensures the build date is always up-to-date and eliminates manual updates.
For instance, with Webpack, you can use the DefinePlugin to create a global variable that stores the build date. This variable can then be accessed within your application code to display the information dynamically.
Leveraging build tools not only automates the process but also allows for greater flexibility, enabling you to format the date according to your specific needs and integrate it seamlessly within your application’s user interface.
Displaying the Build Date in HTML
Directly embedding the build date within your HTML is a straightforward approach, particularly useful for static websites. This can be achieved through server-side scripting or by using a build process as described above. One method involves using a placeholder within your HTML file that gets replaced with the actual build date during the build process. This dynamic replacement ensures accuracy and avoids manual updates.
For example, you could include a <span id="build-date"></span> element in your HTML and then use JavaScript to populate it with the build date retrieved from a variable generated by your build tool.
This direct approach offers a simple and effective way to prominently display the build date, making it easily accessible to users.
Displaying Build Date in JavaScript
JavaScript provides a dynamic way to display and format the build date within web applications. By fetching the timestamp generated during the build process, JavaScript allows you to display the date in various formats and locations within your application.
Consider a scenario where the build date is stored in a global variable. Using JavaScript, you can access this variable and then update a designated HTML element with the formatted date information. This approach offers flexibility and allows for dynamic updates without requiring a full page reload.
This method is particularly useful for single-page applications and dynamic web pages where content updates are frequent.
Best Practices and Considerations
Regardless of the chosen implementation method, following best practices is crucial for ensuring accuracy, maintainability, and user experience. Version control systems play a vital role in accurately tracking changes and providing a reliable source for the build date. Consistent formatting of the displayed date enhances readability and professionalism.
Choosing the right display location within your application’s interface is essential for user accessibility. Footers, about sections, or dedicated update logs are common locations. Transparency and clear communication about the meaning of the build date build trust with users and enhance the overall user experience.
Consider accessibility standards when formatting and displaying the date. Using semantic HTML and ARIA attributes (Accessible Rich Internet Applications) ensures the information is accessible to users with disabilities, such as those using screen readers.
- Automate the process using build tools.
- Choose a clear and consistent date format.
- Integrate the build date into your build process.
- Select the appropriate display location.
- Test thoroughly across different browsers and devices.

Question & Answer :
I currently have an app displaying the build number in its title window. That’s well and good except it means nothing to most of the users, who want to know if they have the latest build - they tend to refer to it as “last Thursday’s” rather than build 1.0.8.4321.
The plan is to put the build date there instead - So “App built on 21/10/2009” for example.
I’m struggling to find a programmatic way to pull the build date out as a text string for use like this.
For the build number, I used:
Assembly.GetExecutingAssembly().GetName().Version.ToString()
after defining how those came up.
I’d like something like that for the compile date (and time, for bonus points).
Pointers here much appreciated (excuse pun if appropriate), or neater solutions…
Jeff Atwood had a few things to say about this issue in Determining Build Date the hard way.
The most reliable method turns out to be retrieving the linker timestamp from the PE header embedded in the executable file – some C# code (by Joe Spivey) for that from the comments to Jeff’s article:
public static DateTime GetLinkerTime(this Assembly assembly, TimeZoneInfo target = null) { var filePath = assembly.Location; const int c_PeHeaderOffset = 60; const int c_LinkerTimestampOffset = 8; var buffer = new byte[2048]; using (var stream = new FileStream(filePath, FileMode.Open, FileAccess.Read)) stream.Read(buffer, 0, 2048); var offset = BitConverter.ToInt32(buffer, c_PeHeaderOffset); var secondsSince1970 = BitConverter.ToInt32(buffer, offset + c_LinkerTimestampOffset); var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc); var linkTimeUtc = epoch.AddSeconds(secondsSince1970); var tz = target ?? TimeZoneInfo.Local; var localTime = TimeZoneInfo.ConvertTimeFromUtc(linkTimeUtc, tz); return localTime; }
Usage example:
var linkTimeLocal = Assembly.GetExecutingAssembly().GetLinkerTime();
Note: this method works for .NET Core 1.0, but stopped working after .NET Core 1.1 - it gives random years in the 1900-2020 range.
