I was just wondering whether there is a *more elegant* way to adjust
the time by 1 minute using batch? I know I could use soon/rsoon (in
this case) but I wanted something portable.

@echo off
setlocal
time /t > %temp%\time
for /f "delims=: tokens=1,2" %%a in (%temp%\time) do (set t1=%%a &set
b=%%b)
echo %b% | find "PM" & if not errorlevel = 1 (set /a
t1="%t1:~0,2%+12") else (set /a t1=%t1:~0,2%)
set /a t2="%b:~0,2%+1"
::at "%t1%:%t2%" %1%

thx

What happens when you execute the preceding at 59 minutes past the hour?

Off sideways...
The CMDTIME commandline utility can sync the local clock via NTP and
includes and "offset" switch (+mm) that can adjust the local clock to
be set mm minutes in advance ("fast") of the official time.

Have no idea if this would be useful to your solution though.
