55ec505e04SMike Pritchard.Sh BUGS
56ec505e04SMike PritchardOn many systems,
57ec505e04SMike Pritchard.Fn resettodr
58ec505e04SMike Pritchardhas to convert from
59ec505e04SMike Pritchard.Va time
60ec505e04SMike Pritchardto a time expressed in terms of year, month, day, hours, minutes,
61ec505e04SMike Pritchardand seconds.  Many of the implementations could share code, but do not.
