Jira Bridge - Syncing timelogs

Do you know if this is possible?
In the example task_issue_handler, it only syncs the sg bid field with Jira’s “timetracking” field (which should, at least in our case, sync with timeoriginalestimate field; although that might be site-specific).

I assume it requires the development of a new handler for timelog entities, so they can be synced directly with Jira timelog entries? eg a non trivial task!

Has anyone managed to sync actual time logged? If so, was there a shortcut to getting this up and running that I’m overlooking?

Thanks in advance for your help!
