+        The SRFI-19 implementation was completely broken.  Already the
+       reference implementation did not handle DST and time zones
+       properly and relied on non-R5RS-isms like passing reals to
+       `quotient'.  For Guile, some additional fixes were needed because
+       of the incomplete numeric tower implementation.  See also
+       srfi-19.test. 
+       
+       * srfi-19.scm (date-zone-offset): Fixed typo in export clause.
+       (add-duration): Renamed from priv:add-duration. 
+       (priv:time-normalize!): Handle fractional nanoseconds; remove
+       duplicate definition.
+       (priv:current-time-tai): Fixed typo.
+       (time=?, time<=?): Fixed typos.
+       (time-tai->time-utc, time-utc->time-tai,
+       time-utc->time-monotonic): Use make-time-unnormalized instead of
+       make-time when uninitialized time fields are used.
+       (set-date-nanosecond!, set-date-second!, set-date-minute!,
+       set-date-hour!, set-date-day!, set-date-month!, set-date-year!,
+       set-date-zone-offset!): Define.
+       (priv:local-tz-offset): Take an extra argument in order to handle
+       DST effects.
+       (time-utc->date, time-tai->date, time-monotonic->date): Handle the
+       changed signature of priv:local-tz-offset. Don't pass non-integer
+       arguments to quotient (non-R5RS, not supported by Guile). 
+       (date->time-utc): Ensure that seconds in a date structure are
+       always exact integers.  Handle DST properly.
+       (current-date, julian-day->date, modified-julian-day->date):
+       Handle the changed signature of priv:local-tz-offset.  
+       (julian-day->time-utc): Reverted earlier inexact->exact hack;
+       make-time now handles inexact arguments.
+       (priv:locale-print-time-zone): At least print the numerical time
+       zone. 
+       (priv:integer-reader): Fixed named let iteration.
+       (priv:read-directives): Use set-date-month! instead of
+       priv:set-date-month! etc.
+       (string->date): Handle DST properly.

        * srfi-13.scm: Prevent `export' from re-exporting core bindings.
