Azure Release Notes Wiki Markdown date - azure-devops

Question

I am completely new to this so any help and explanation would be appreciated.
I have a created a template that will generate my release notes in our wiki. I am using the Generate Release Notes Markdown (crossplatform) extension by Richard Fennell.
In the template section of the extension, I use this short and simple template:
# {{releaseDetails.name}}
**Date** : {{releaseDetails.modifiedOn}}
**Build Number**: {{buildDetails.buildNumber}}
{{#forEach workItems}}
{{#if isFirst}}## Work Items{{/if}}
- **{{lookup this.fields 'System.WorkItemType'}}** #{{this.id}}
{{/forEach}}
The output is as follows:
Release-17
Date : Mon Dec 05 2022 18:19:37 GMT+0000 (Coordinated Universal Time)
Build Number: 20221026.4
Everything is good except I would like to change the date and time format to just show Mon 12/05/2022 12:19 PM. That's it. I don't want the military time or the GMT +0000 stuff in there.
EX:
Release-17
Date : Mon 12/05/2022 12:19:37 PM
Build Number: 20221026.4
Does anyone know how to format the date properly? Any help is appreciated.
Thanks!
Searched forums and have not been able to find any solutions.

To modify the time zone and date format in Generate Release Notes Markdown, you need to add custom Javascript extenstion module in the Generate Release Notes Markdown task -> Custom Handlebars Extension.
Here is an example:
Javascript module
module.exports = {date_formatter(theDate) {
return theDate.toLocaleString("location");
}};
Task sample:
- task: XplatGenerateReleaseNotes#3
displayName: 'Generate Release Notes based on Release Comparison API'
inputs:
outputfile: '$(System.DefaultWorkingDirectory)/releasenotes.md'
templateLocation: InLine
inlinetemplate: |
# {{releaseDetails.name}}
**Date** : {{date_formatter releaseDetails.modifiedOn }}
**Build Number**: {{buildDetails.buildNumber}}
{{#forEach workItems}}
{{#if isFirst}}## Work Items{{/if}}
- **{{lookup this.fields 'System.WorkItemType'}}** #{{this.id}}
{{/forEach}}
replaceFile: true
customHandlebarsExtensionCode: |
module.exports = {date_formatter(theDate) {
return theDate.toLocaleString("location");
}};
Refer to this sample: date_formatter.js and Handlebar Extensions
