Programmable calculators with real-time clock

[Dave Britten]

I'm trying to come up with a list of programmable calculators that have a real-time clock that can be accessed from programs. I know of a few off the top of my head, but haven't been able to track down too many. What other ones are out there?

HP 48/49/50
HP 28 (I think there might be some SYSEVALS that get you crude access to a clock)
HP 41 (Time Module or CX, also DM 42)
TI-89 Titanium
TI Voyage 200
TI-84 (I think most forms of the 84 have one)

What about the Prime, or the various TI-Nspires? And how about other brands like Casio or Sharp?

The HP27S Solver has functions that return the current time or date, and functions to do date/time arithmetic. The palmtops (Hp95lx/100lx/200lx) also have the same Solver capability, if you want to extend your definition of calculator a bit.

Do the 17B or 19B models have those functions too? I totally can't remember if I've seen them on those before.

I just checked; the 19B & 17Bii indeed have the same functions. The 18B lacks the current time/date functions, so it wouldn't qualify.

Oops, correction: the 19Bii has these functions. Not sure about the 19B though.

I think the only significant difference with the 19BII was the addition of RPN, so the 19B probably has them.

And I suppose Lotus 1-2-3 on the HP palmtops would qualify. I've used the date and time functions quite a bit.

I don't know if you want to include the 71 since it's in a somewhat different league, but it has it too of course, and I have no doubt the 75 did. I'd be lost without the RTC and associated functions in my 41cx. I use them all the time.

And there are two programmable LED calculators with real time clock, accessible from programs: HP-25E GPS and HP-29E GPS. :-)

The HP Prime has a clock and you can use the System.Date and System.Time variables to access the values in a raw (i.e. useful but not "user friendly") format.

[Paul Dale]

The WP 34S has a real time clock if the crystal installed.

What about 9825? It has a LED display, is programmable and there is an add-on real time clock for it.

Perhaps DM41?

Oh yeah, that's what I meant. Do we know if the DM 42 will have time functions?

And let's not forget Katie's RTC for the HP-97/97S.

I find the RTC, beeper and the alarm/programmable functionality of the 48 most handy for alarm clock and audible clock functions.

Yeah, the 48 (and its descendants) has probably the most RTC functionality of any that I've seen so far.
