Version Control with Subversion - Electrical and Computer ...

$ svn update --revision PREV foo.c
# rewinds the last change on foo.c
# (foo.c's working revision is decreased)
These keywords allow you to perform many common (and helpful) operations without having to look up
specific revision numbers or remember the exact revision of your working copy.
Revision Dates
Anywhere that you specify a revision number or revision keyword, you can also specify a date inside
curly braces “{}”. You can even access a range of changes in the repository using both dates and revisions
together!
Here are examples of the date formats that Subversion accepts. Remember to use quotes around any date
that contains spaces.
$ svn checkout --revision {2002-02-17}
$ svn checkout --revision {15:30}
$ svn checkout --revision {15:30:00.200000}
$ svn checkout --revision {"2002-02-17 15:30"}
$ svn checkout --revision {"2002-02-17 15:30 +0230"}
$ svn checkout --revision {2002-02-17T15:30}
$ svn checkout --revision {2002-02-17T15:30Z}
$ svn checkout --revision {2002-02-17T15:30-04:00}
$ svn checkout --revision {20020217T1530}
$ svn checkout --revision {20020217T1530Z}
$ svn checkout --revision {20020217T1530-0500}

When you specify a date as a revision, Subversion finds the most recent revision of the repository as of
that date:
$ svn log --revision {2002-11-28}

Is Subversion a Day Early?
Guided Tour
If you specify a single date as a revision without specifying a time of day (for example 2002-11-27), you
may think that Subversion should give you the last revision that took place on the 27th of November. Instead,
you'll get back a revision from the 26th, or even earlier. Remember that Subversion will find the most recent
revision of the repository as of the date you give. If you give a date without a timestamp, like 2002-11-27,
Subversion assumes a time of 00:00:00, so looking for the most recent revision won't return anything on the
day of the 27th.
If you want to include the 27th in your search, you can either specify the 27th with the time
({"2002-11-27 23:59"}), or just specify the next day ({2002-11-28}).
You can also use a range of dates. Subversion will find all revisions between both dates, inclusive:
