Custom Fields in email notifications

[Joshua Keele]

So I am having an issue including some custom fields in an email. 
For example I have created a custom field "Start:" which is a date time picker type field. 
No matter how I try to format the result is blank. I have even used the rest API to discover the custom field id. Any help would be appreciated. Here are the examples I have attempted:
{{Start:.value}}
{{customfield_10050.value}}
{{issue.fields.Start:}}
{{issue.fields.Start:.value}}

Also note, I have been successful including other custom fields in an email and they work as expected. For example I have a custom field "Select Affected Services:." which is a checkboxes field type, and the following includes tha value
{{Select Affected Services:.value}}

Thanks in advance

Will the following work?

{{issue.Start}}

[Joshua Keele]

no but I did just get the following to work:
{{issue.customfield_10050}}

Now my concern is it returns the GMT form not the formatted offset time. Is there a way to overcome that?

example:
Start:
2022-02-07T08:00:00.0+0000

The actual start time was 00:00 (12am)

so apparently {{issue.Start:}} works as well, but again not formatted for my time zone settings, which do display correctly in Jira itself

[Jack Brickey]

does the documentation on date formatting help? jira-smart-values-date-and-time 

[Joshua Keele]

The format looks much nicer, but does not accommodate for time zone
It shows as Coordinated Universal Time. 
Is there a place in Jira config that I have failed to set the appropriate time zone?
Under system General Configuration, Default user time zone, is (GMT-08:00) Los Angeles

Monday, February 7, 2022 at 8:00:00 AM Coordinated Universal Time

[Joshua Keele]

particularly interesting as the documentation actually shows the time as adjusted for time zone

[Joshua Keele]

I am still unable to get this to display the corrected offset time for the time zone specified as default
