Author Signature

A signature contains the author and timestamp of a commit. Each commit includes a signature of the author and committer (which can be identical).

git_signature_default(repo = ".")

git_signature(name, email, time = NULL)

git_signature_parse(sig)

Arguments

repo	The path to the git repository. If the directory is not a repository, parent directories are considered (see git_find). To disable this search, provide the filepath protected with I(). When using this parameter, always explicitly call by name (i.e. repo = ) because future versions of gert may have additional parameters.
name	Real name of the committer
email	Email address of the committer
time	timestamp of class POSIXt or NULL
sig	string in proper "First Last <your@email.com>" format, see details.

Details

A signature string has format "Real Name <email> timestamp tzoffset". The timestamp tzoffset piece can be omitted in which case the current local time is used. If not omitted, timestamp must contain the number of seconds since the Unix epoch and tzoffset is the timezone offset in hhmm format (note the lack of a colon separator)
