Hi.  I'm seeking a real time clock chip that as a minimum can provide
month/day/year/day-of-week information as well as leap year
compensation and a configurable daylight savings time compensation.
In particular, for the daylight savings time I would like to be able
to configure the start and end dates and the amount of time
added/negated for the transition.

A Hitachi part has been suggested, but the one I was shown doesn't
have the daylight savings time compensation function.  BCD output is
preferable and I really only need one interrupt on a once-per-second
basis.

Does anyone have any chip suggestions?

Thanks in advance - Susan M. Prothro
