#16433: infinite recursion in torsocks log timestamps
-------------------------+-------------------------

 Priority:  normal       |      Milestone:
Component:  Torsocks     |        Version:
 Keywords:  netbsd       |  Actual Points:

-------------------------+-------------------------
 If libc calls `open` and `close` in order to deal with time zones for
 `localtime`, the torsocks interception of `close` may lead to infinite
 recursion: torsocks `close` tries to print a log message, which needs a
 timestamp, which it formats with `localtime`, which opens the tz database
 and calls `close` when done, which tries to print a log message, which
 needs a timestamp...

 (NetBSD's libc is an example of such a libc.  Note `gmtime` has the same
 property.)

 The attached patch changes timestamps to be seconds since epoch minus leap
 seconds, i.e. a standard POSIX clock, in order to avoid this recursion.
