Shows a pretty analog clock and the calendar of the current month, preferably when you turn on your calculator. Same as CStart but doesn't start automatically.
Update of the below program. Includes ten clocks, such as a unique abacus clock, a gauge clock, several digital clocks, and an ordinary round analog clock.
Keeps the system clock as accurate as possible by synchronizing the clock with a time standard, and using the accumulated adjustments with the elapsed time to compute the necessary correction amount/rate.
Contains several functions, including a chronometer by pressing A, a count-down timer with B, a periodic beep with C, an alarm with D, and a ticking clock with E.
Specific timer for darkroom applications. Gives count down for total development times, gives intermediate alarms every 60 seconds for tank agitation, uses large digits, and more.
The program creates a variable containing the JMFD's mnemonics string for the specific date, either using the HP 48 command DATE or any other in the format, the string "An15Tue2.002" is stored in 'An15Tue2.002' variable.
Automatically adjusts the 48G/GX calculator's clock for daylight savings time as defined in the United States (prior to 2007). Includes PDF and PostScript documentation.
Timed evaluation of object, returning results in both ticks and seconds. Two programs (one for the 48 and 49 series, and the other for the 28 series) are provided as User RPL source code within the text file. These work correctly with any wordsize, and compensate for the time used by the program. Minor modification to match the individual calculator is required.
Digital clock for the G series, with fading numbers. The library is written in System RPL and assembly language and uses the calculator's system clock which configures a system interrupt to activate every second.
Fast and easy to use calendar program. Shows the current month or an arbitrary day. Commands to increase/decrease the month/year help for fast navigation.
God's HolyDays. Compute the HolyDays from -3761 (3762BC) to 2499 AD. This show you the Annual HolyDays (Spring: Passover, Days of Unleavened Bread, Pentecost) and (Fall: Trumpets, Atonement, Feast of Tabernacles, Last Great Day).
Source code (only) of an interrupt-driven digital clock with big numbers. Meant to be an example of how to make use of calculator system clock activation interrupt. It enables low power consumption between screen updates. Program is small, because it does not contain IRQ handlers itself and does not mess with system time counters.
This is "Yet Another Calendar", but it is international. It displays the calendar according to the system flag of the HP by building a European or USA format calendar.
The program creates a list (best viewed using JAVA LIB) containing the JMFD's preferred string for the actual date, storing it in the variable AHORA48 in the format: { { "Tuesday, January 15, 2002" } {19.3421 } }
Analog ticking clock for the G series. The program is written in System RPL and uses the calculator's system clock which configures a system interrupt to activate every second.
This is a bundle of two time calculating programs. One calculates one single time period, the other calculates multiple time periods. You must remember to into the times in military for the program to work correctly. i.e. 2 pm is 14.0000 (hh.mmss). Enter times a read from the clock, then program calculates the elapsed time into the decimal of time, i.e. 2:30 pm to 3:00 pm would be 0.5 hrs. These programs are useful in calculating time for work or laboratory application.
Extended Time, Date, Calendar and Astronomical routines for the HP 48G(X) and 49G(+). Part of these routines are ported from the invaluable HP-41C CALENDARS Users' Library Solutions. The astronomical routines include calculation of times of sunrise, transit and sunset, moon phases, and seasons.
