Hello All,

I tried using the command prompt to change the time by one hour, but
couldn't quite get it to work. What I am looking to do is perform a function
on the current system time. I have a remote computer that has a limited user
account and can't change the clock. I want to create a batch file, burn it to
a disk and let them run that. What I was trying was to add 01:00:00 to the
current time from the command prompt, but I think this is beyond my
abilities. Any help would be greatly appreciated.

As an afterthought: If your users run the command twice then they will
advance the clock by two hours!

Thank you for the quick response. In testing I received the error 'New Time'
is not recognized as an internal or external command, and the command prompt
closes.

I just copied it and pasted into notepad, saved it as a .bat file, ALL Files
under file type. Is this just operator error?

THanks

You can get them to run this batch file:
@echo off
for /F "delims=:" %%a in ('echo %time%') do set /a hour=%%a + 1
for /F "tokens=2* delims=:" %%a in ('echo %time%') do set
NewTime=%hour%:%%a:%%b
echo Setting the time to %NewTime%
rem time %NewTime%

To test it, run it as it is. To activate it, remove the word "rem" in the
last line.

Note: Do not retype this batch file. Use copy & paste instead.

This happens because your newsreader broke up the batch file lines and you
did not "unbreak" them. Here is a line-numbered version of the same batch
file so that you can see clearly where each line starts:
1. @echo off
2. for /F "delims=:" %%a in ('echo %time%') do set /a hour=%%a + 1
3. for /F "tokens=2* delims=:" %%a in ('echo %time%') do set
NewTime=%hour%:%%a:%%b
4. echo Setting the time to %NewTime%
5. echo time %NewTime%

Thanks Pegasus, it worked brilliantly!

And yes, my typical user definitely has the ability to double click on the
..bat file about a hundred times to screw it up. Maybe I will go "Mission
Impossible" on them and send a CD that self destructs after one use.

Thanks again, you just improved my day by a factor of 100.

Thanks for the feedback. You can, of course, prevent your user from changing
the time more than once, e.g. like so:

01. @echo off
02. set FlagFile=c:\TimeChange.txt
03. if exist %FlagFile% (
04. echo %UserName% attempted to change the time on %date% at %time% >>
%FlagFile%
05. echo.
06. echo You have already advanced the PC's time. Can't do it twice . . .
07. goto Exit
08. )
09.
10. echo Time changed on %date% at %time% by %UserName% > %FlagFile%
11. for /F "delims=:" %%a in ('echo %time%') do set /a hour=%%a + 1
12. for /F "tokens=2* delims=:" %%a in ('echo %time%') do set
NewTime=%hour%:%%a:%%b
13. echo Setting the PC's time to %NewTime%
14. time %NewTime%
15.
16. :Exit
17. echo.
18. echo Press the Space Bar to close this window.
19. pause > nul
