Issue Summary

In some timezones, using Jira automation to copy date picker entries results in the date 1 day off.

Steps to Reproduce

1. Install Automation for Jira https://marketplace.atlassian.com/apps/1215460/automation-for-jira-server?tab=overview&hosting=datacenter
2. Set system / local timezone to AEST (Australian Eastern Standard Time) | GMT + 10
3. Create a custom field - date picker. Lets call it Start Date
4. Make start date available on the project screen
5. Create an automation rule that copies the Start Date to Target Start. Target Start isn't natively modifiable so you'd need to use something similar to the .JSON below to modify the custom target start date.

   {
       "fields": {
           "customfield_10101":"{{issue.customfield_10901}}"
       }
   }

Expected Results

Dates are the same

Actual Results

Dates are off by one day

Workaround

You can use plusDays to offset the bug. Example

{
    "fields": {
        "customfield_10101":"{{issue.customfield_10901.plusDays(1)}}",
    }
}
