If you remove and replace your batteries...you will not lose the memory. The unit will store up to 90 measurements in non-volatile memory...so it will stay there.

I have the same unit and use these directions....and never had issues with setting the date and time.

Hi here a link to Canon P23-DTSC Calculator User Manua....CHEERS
http://office.manualsonline.com/manuals/mfg/canon/p23dtsc.html

Is it set to auto update from a time server? Right click on the clock in the taskbar, select adjust date/time. On the internet time tab, click advanced settings. I would recommend using time-a.nist.gov instead of time.windows.com

You weren't precise if the change was due to Daylight Savings Time or just a general need to change the time so I'm giving you the complete set of instructions for changing the time

Setting the Time
Note: Use 24 hour and 60 minute format when setting the time.
For example: 2:00 pm = 14:00.
1. To make changes to your clock’s time setting, you must first put the clock into Program mode. See
section Accessing Program Mode to Update Calendar, Time and DST for instructions. When the
display flashes P1 dAtE, press the ◄ left button until P2 CL oc appears, then press the ● right
button.
2. Press the ◄ left button to choose 12-hour AM/PM display or 24-hour military time, then press the ●
right button.
3. Press the ◄ left button until the correct hour appears, then press the ● right button.
4. Press the ◄ left button until the correct minutes appear, then press the ● right button.
5. When the display flashes the correct time, press the ● right button.
6. The display flashes P2 CL oc again. To make changes to the DST start date or DST end date, press
the ◄ left button one time until P3 BDLE appears in the display and continue to How to Set the
Begin Date for DST. Otherwise, press the ◄ left button several times until END appears, and select
the ● right button to save your updated settings.
How to Disable DST
To disable Daylight Saving Time, set the DST beginning date equal to the ending date (i.e., DST begin
date = 08-03-09; DST end date = 08-03-09).
See next for details regarding setting the DST begin date and end date. Typically, clocks operating in
Arizona, Hawaii and Puerto Rico do not observe DST, and disabling the DST function typically applies to
those areas only.
By default, and unless otherwise modified, DST takes effect on the first Sunday in April and ends on the
last Sunday in October (this was the United States standard through 2006).
How to Set the Begin Date for DST
Note that in 2007 the standard for DST changes to a different start date and end date. The steps below
correct the change in the new start date for DST. The new start date and end date need only be changed
once, since the clock’s rolling calendar function auto-calculates the start date and end date for DST every
year thereafter.
Note that if the begin date for DST has passed, in addition to modifying the begin date (and end date),
you will also need to modify the time.
1. When the display flashes P1 dAtE (see earlier section Accessing Program Mode to Update
Calendar, Time and DST for instruction), press the ◄ left button until P3 bdLt appears, then press
the ● right button.
2. Press the ◄ left button until the correct year appears, then press the ● right button.
3. Press the ◄ left button until the correct month appears, then press the ● right button.
4. Press the ◄ left button until the correct date appears, then press the ● right button.
5. When the display flashes the correct year, month and date, press the ● right button.
6. When the display flashes P3 bdLt, press the ◄ left button once to select next menu option, P4
EdLt, which provides a way to set the end date of the Daylight Saving period.

How to Set the End Date for DST
Note that in 2007 the standard for DST changes to a different start date and end date. The steps below
correct the change in the new end date for DST. The new start date and end date need only be changed
once, since the clock’s rolling calendar function auto-calculates the start date and end date for DST every
year thereafter.
1. When the display flashes P4 EdLt (see conclusion of previous section How to Set the Begin Date
for DST for instruction), press the ● right button.
2. Press the ◄ left button until the correct year appears, then press the ● right button.
3. Press the ◄ left button until the correct month appears, then press the ● right button.
4. Press the ◄ left button until the correct date appears, then press the ● right button.
5. When the display flashes the correct year, month and date, press the ● right button.
6. The display flashes P4 EdLt again. Press the ◄ left button several times until END appears, and
select the ● right button to save your updated settings.
Note: To disable the Daylight Saving Setting, set the beginning and ending date to the same date.

Hi there.
Download the latest bios update for that model motherboard or PC, install it and restart the PC, time and date should stay once set .

Good luck and thanks for using FixYa!!

I suggest u to contact the service people and they will change the internal battery to keep update with time and date. Every camera has internal small battery so has to change regularly

ok, have your calculator set on "on" press the "time/clock" button once, when date appears on calculator press the "M+=" and hold until first number on date flashes, enter the date you want, when done switch your calculator from "on" to "print". date should be saved. do the same for time.

This little guy has the most complicated date setting procedure I have ever seen! From the manual: "Manual Time and Date Settings 1. To change your time setting, press and hold the J Time Set Button so that the clock display begins flashing. 2. While the display flashes, press the 1 Reverse and 6 Forward Buttons to set the time. Hold a button for a few seconds to set the time rapidly. Be sure to set the correct AM/PM time, shown by the PM Indicator. 3. After setting the time, press the 4 Enter Button or wait about ten seconds for the clock to beep twice and the setting to lock into place. 4. To change the calendar, press and hold the 9 Date/7-5-2 Button until the display shows the flashing year. 5. Press the 1 Reverse and 6 Forward Buttons to set the current year. When you have selected the year, press the 4 Enter Button, then use the 1 Reverse and 6 Forward Buttons to set the month/day. 6. After you have set the date, press the 4 Enter Button or wait for the display to beep twice and lock into place."
