Add date & time to batch filename in YMD format

Question

I am using the following batch script:

@echo off

set host=upc.hu

set logfile=%host%.log

echo. >> %logfile%
for /f "tokens=*" %%A in ('ping %host% -n 1 ') do (echo %%A>>%logfile% && GOTO Ping)

:Ping
for /f "tokens=* skip=2" %%A in ('ping %host% -n 1 ') do (
    echo %date% %time:~0,2%:%time:~3,2%:%time:~6,2% %%A>>%logfile%
    echo %date% %time:~0,2%:%time:~3,2%:%time:~6,2% %%A
    timeout 1 >NUL 
    GOTO Ping)

I need to add the date in YMD format and the time in HM format e.g:`

2017.06.02 12:39 Log_%host%.log (Would prefer 20170602 1239 format)

Tried to set the date and add it to the logfile name but I have some kind of problem with the syntax because only the the year added or nothing at all. Could you help me with the script?

EDIT:

Tried to add only %date% to the logfile like this:

set logfile=%date%.log

If I simply echo the date it works just fine but the file name is 2017 without the month, day and .log part.

@SamDenty Thanks, I tried to add to the logfile after setting the date but still got the same issue. Nothing shown when the file is created, only the %host%.log name. — 2b1c, Jun 03 '17 at 11:16
