Hi, how can I get list of all hours worked for specific user/users in current/last month?

I added widget My spent time to URL /my/page, but there is only week view. It is unusable for my use case.

My employees need to know number of hours that spent on all of my project (one project per customer) during last/current month.

Is there any way how can I do it?

For example: Redmine has a plugin for that: https://github.com/eyp/redmine_spent_time

Thanks.
