I am interested in modern warfare, especially Russia 1942-43, World War I & II also, with many years of knowledge in such fields.
I also try to encourage people to distinguish between using Wikipedia as a tool for research and a sole independant source on a project, as I observed friends at my time at university and I was often shocked at the lack of cross-referencing and care taken with research. But I do think wikipedia is a fantastic resource, if used appropriately, and I became an administrator to encourage this.
If you do this, Wikipedia will show all times in Recent changes, page histories, and contribution histories based on your local time zone. However, when you sign a talk page with ~~~~, the timestamp is created in text, so it has to be displayed in UTC. Automated logs such as image file uploads are also shown in server time (UTC).
To show other users what time zone you are in, you could even add a time userbox to your own user page.
