You can start a timer from any application and stop it inside Jira issue, so your work-log item will be added with data based on stopped time entry. To make it happen you have to specify the Jira issue key in the description of the time entry, like: “RET-12 issue-summary-here“, where “RET-12“ is Jira issue key.
Jira work-log items

For each running timer that we try to stop inside the Jira issue details page the application, automatically, will validate and if possible - add a new Jira work-log item based on the information (description, start date-time, duration) from the stopped time entry and behalf the Jira user who has stopped it.
