Implementation Guide

In this section, we’ll cover customizing date-time formats and applying time zone offsets when rendering email messages using GroupDocs.Viewer .NET.

Customizing Date-Time Format in Emails

Setting a custom date-time format allows alignment with specific business or regional standards. Follow these steps:

Step 1: Load the Email Document

Create an instance of Viewer to load your email document.

using (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY\\Sample.eml"))
{
    // Further code will go here
}

Step 2: Define HTML View Options

Specify how you want the emails rendered using HtmlViewOptions.

// Specify output directory and file name for the rendered document
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string filePath = Path.Combine(outputDirectory, "output.html");

HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(filePath);

Step 3: Set Custom Date-Time Format

Customize the date-time format using DateTimeFormat.

// Set a custom date-time format (e.g., Month day year Hour:Minute AM/PM timezone)
options.EmailOptions.DateTimeFormat = "MM d yyyy HH:mm tt zzz";

Step 4: Apply Time Zone Offset

Adjust the time zone offset to ensure all times are displayed in your desired timezone.

// Set a time zone offset of +1 hour
options.EmailOptions.TimeZoneOffset = new TimeSpan(1, 0, 0);

Step 5: Render Document with Options

Render the document using the specified view options.

viewer.View(options);

Troubleshooting Tips

  • Incorrect File Path: Verify that your file paths are correctly set for both input emails and output directories.
  • Time Zone Mismatch: Double-check the time zone offset value to ensure it aligns with your requirements.

Practical Applications

Customizing date-time formats and applying time zone offsets can be useful in various scenarios:

  1. Business Communications: Aligning email timestamps with company headquarters’ time zones for better coordination.
  2. Global Projects: Ensuring team members from different regions view consistent date-times.
