I would like to send a command-line output to a file named with the current date and time.
I tried this but it did not worked:

net view >> C:\Temp\%date%%time.txt

How can I do it?

Replace the / and : with nothing.
net view >> "C:\Temp\%date:/=%%time::=%.txt"

Basically removing those invalid filename characters. You could replace with _ or - if you wish.
net view >> "C:\Temp\%date:/=_%%time::=-%.txt"

If you want to keep the files, the format of %date% is no good. It MIGHT contain the weekday, and mm/dd/yyyy is something strange to look at and sort for. If this is for temporary issues, keep the simple approachs shown above.

The issue was certainly either of the explanations given above, ie. the / characters in the date that cannot be used in file names, or unwanted spaces and days of the week in the DATE output, but aside from that you need to be careful to check your code for things like missing % in your variables.  In your code you missed the closing % off the TIME variable:

depending on how your date/time is displayed, here's a batch file that might be handy
my date shows as 10/07/2009
my time shows as 16:04

@echo off
for /f "tokens=1,2,3 delims=/" %%i in ('date /t') do (
set day=%%i
set month=%%j
set year=%%k
for /f "tokens=1 delims= " %%i in ("%year%") do (
set year=%%i
for /f "tokens=1,2 delims=:" %%i in ('time /t') do (
set hour=%%i
set minute=%%j
echo %year%-%month%-%day%-%hour%-%minute%
