Issue Summary

When adding a workflow transition validator to check if a Date Time Picker type custom field is valid against a now expression, for example:

Even if the condition is true, there is a time difference between the time the Custom Field has and the actual time being reported by Jira.

Steps to Reproduce

1. Create a Date Time Picker type custom field.
2. Create a workflow transition and add a validator to compare the date/time field value with the current time being reported by Jira.

Expected Results

The condition is respected and the status is transitioned or not as limited by the time in the condition.

Actual Results

The condition is not respected because there is a time difference between the time filled in and the now expression used.

Workaround

Fill the time gap with the additional hours required for the condition to be respected. For example:

{{now}} / {{now.minusHours(3).shortTime}} 

The number of hours required is the offset from GMT in the site's default timezone set in System > General configuration > Internationalization.

Eg. in a site set to 'Singapore (+8)' the "now" value used by the validator will be 8 hours in the future, but sites set to 'London (+0)' will have the correct value for "now".
