I realize that this could probably be done easier in any number of other scripting languages but started to do it quick in cmd and now Im curious.

Looking to start a process at an offset to the time that another process started. Lets say 5 minutes to keep it simple. Is there a way to add to the %TIME% variable?

For instance:

start /b foo.exe
at %TIME% + 5 minutes bar.exe

Thanks for any assistance

I just typed set/? and discovered cmd is much better than old bat... :-)

set h=%TIME:~0,2%
set m=%TIME:~3,2%
set/a m2="m+5"
set t2=%h%:%m2%
set t2

Obviously, you can get 62 minutes, etc., I let you do the extra math... :-D

When m starts with 0, it expects an octal number, so 08 and 09 are invalid and parsed as zero. set/a m2="9+1" => 10, but set/a m2="09+1" => Invalid number. Numeric constants are either decimal (17), hexadecimal (0x11), or octal (021).
The workaround for the above is to do set/a m2="1m-100+5" (or %%100).

Here is the extra math:

:: Get an offset of 1 minute from the current time, accounting for edge cases
set hr=%TIME:~0,2%
set /a mn=%TIME:~3,2%+1
:: check minutes; greater than 60? add n/60 to hour, n%60 to mins
if %mn% geq 60 set /a hr=hr+mn/60 && set /a mn=mn%%60
if %hr% geq 24 set /a h=0
:: pad zeros if necessary
if %mn% leq 9 set mn=0%mn%
if %hr% leq 9 set hr=0%hr%

thanks

My bath code:

set h=%TIME:~0,2%
set m=%TIME:~3,2%
set s=%TIME:~6,2%
set time=%h%_%m%_%s%
mkdir c:\test\%time%
move c:\test\*.* c:\test\%time%
"C:\Program Files\WinRAR\RAR" a -ep c:\test\%time%\ -agDD-MM-YY_hh-mm-ss c:\test\%time%\*.* -zc:\arhiv\HEADERS.TXT
move c:\test\%time%\*.rar c:\arhiv\
rmdir c:\test\%time% /S /Q

copy.cmd:

set hr=%TIME:~0,2%
if %hr% leq 9 set hr=0%hr:~1,1%
set mydate=%DATE:~6,4%%DATE:~3,2%%DATE:~0,2%-%hr%%TIME:~3,2%%TIME:~6,2%
copy file.txt file-%mydate%.txt
pause

Extended the "bath code" a little bit:

echo ----- time -----
echo %time%
set _hh=%time:~0,2%
set _mm=%time:~3,2%
set _ss=%time:~6,2%
set __time=%_hh%%_mm%%_ss%
echo _%__time%_
echo ----- time -----
echo:
echo ----- date -----
echo %date%
set _Y=%date:~0,4%
set _M=%date:~5,2%
set _D=%date:~8,2%
set __date=%_Y%%_M%%_D%
echo _%__date%_
echo ----- date -----
pause

Outputs 205146 for %__time%

Outputs 20180613 for %__date%

this fails for other date localizations such as the european 13/12/1234 format
