 NOTE: This doesn't check all time zones -- it merely determines that
 the configuration option is taking effect.
 
 An arbitrary (U.S.) time zone is used here.  TZ=US/Hawaii is selected
 since it does not use DST (unlike other U.S. time zones) and is always
 a fixed difference from UTC.

   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ hg up -q 2
 
 Modify one of the externals to point to a different path so we can
 test having obstructions when switching branches on checkout:
   $ hg checkout tip
   0 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ echo "obstruct =        [svn]       $SVNREPOURL/externals" >> .hgsub
   $ svn co -r5 --quiet "$SVNREPOURL"/externals obstruct
   $ hg commit -m 'Start making obstructed working copy'
   $ hg book other
   $ hg co -r 'p1(tip)'
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   (leaving bookmark other)
   $ echo "obstruct =        [svn]       $SVNREPOURL/src" >> .hgsub
   $ svn co -r5 --quiet "$SVNREPOURL"/src obstruct
   $ hg commit -m 'Other branch which will be obstructed'
   created new head
 
 Switching back to the head where we have another path mapped to the
 same subrepo should work if the subrepo is clean.
   $ hg co other
   A    *obstruct/other (glob)
   Checked out revision 1.
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   (activating bookmark other)
 
 This is surprising, but is also correct based on the current code:
   $ echo "updating should (maybe) fail" > obstruct/other
   $ hg co tip
   abort: uncommitted changes
   (commit or update --clean to discard changes)
   [255]
 
 Point to a Subversion branch which has since been deleted and recreated
 First, create that condition in the repository.

 Test a subrepo referencing a just moved svn path. Last commit rev will
 be different from the revision, and the path will be different as
 well.
