A document that has been open for many hours shows 00:00:00; several documents that I have been working on for many days always show 00:10:00, while another document, which I worked on for a couple of days, shows 274:31:44. I get paid by the hour for revising documents and the “total editing time” function would be really useful for invoicing my clients. I have LO version 4.2.0.4, English language, running on 64-bit Windows 7, English language. Any help would be appreciated.
