Radicle is an open source, peer-to-peer code collaboration stack built on Git. Unlike centralized code hosting platforms, there is no single entity controlling the network. Repositories are replicated across peers in a decentralized manner, and users are in full control of their data and workflow.

Git records the local timezone when a commit is made [1]. Knowledge of the timezone in which a commit was made could be used as a bit of identifying information to de-anonymize the committer.

Setting one's timezone to UTC can help mitigate this issue [2][3] (though, ofc, one must still be wary of time-of-day commit patterns being used to deduce a timezone).

    It is <unix-timestamp> <time-zone-offset>, where <unix-timestamp> is the number of seconds since the UNIX epoch. <time-zone-offset> is a positive or negative offset from UTC. For example CET (which is 1 hour ahead of UTC) is +0100.

    to set the timezone for a specific command, say e.g. TZ=UTC git commit

    each commit Git stores a author date and a commit date. So you have to omit the timezone for both dates.

    I solved this for my self with the help of the following Git alias:

    [alias]
    co = "!f() { \
        export GIT_AUTHOR_DATE=\"$(date -u +%Y-%m-%dT%H:%M:%S%z)\"; \
        export GIT_COMMITTER_DATE=\"$(date -u +%Y-%m-%dT%H:%M:%S%z)\"; \
        git commit $@; \
        git log -n 1 --pretty=\"Autor: %an <%ae> (%ai)\"; \
        git log -n 1 --pretty=\"Committer: %cn <%ce> (%ci)\"; \
    }; f"
