Dynamic date in batch file - powershell

Question

i am running the following command in a cmd:
Prog.exe -time Components_2016_04_19_11.ss
I want to write a batch file that will be run hourly and i need the date in the command to change accordingly - the date needs to be in the format above, and the last part of the date is the current hour minus 7 hours
So if the time now is 1/1/2016 20:43 the command will look like this
Prog.exe -time Components_2016_01_01_13.ss
i need help creating the appropriate batch file
Thanks

Answer 1

For future reference, questions resembling "Write this for me. Here are my requirements." aren't well-received around here. But this time, just to prevent any more unhelpful answers from being posted, I'll help you out with a solution.
Pure batch is really cumbersome with date math. Compensating for midnight, month changes, leap years, etc. can be a nightmare. It's much easier to use a different language -- one which has a proper Date object that will handle calendar quirks without having to hack around them.
Here's a PowerShell solution to your problem:
Prog.exe -time ("Components_{0}.ss" -f (Get-Date).addHours(-7).toString("yyyy_MM_dd_HH"))
That's it, just a one-liner. If you require a batch script, you can employ the PowerShell helper to perform the date math heavy lifting.
#echo off & setlocal
for /f "delims=" %%I in (
'powershell -noprofile "(Get-Date).addHours(-7).toString('yyyy_MM_dd_HH')"'
) do (
Prog.exe -time Components_%%I.ss
)
goto :EOF

Get-Date
Get-Date | Get-Member

Answer 3

you can use this:
$GBL = 0
do{
Prog.exe
Get-Date
sleep 3600
}
while($GBL -lt 1)
$GBL it's a infinity variable for the loop. inside of the do execute the program and use the sleep for wait 3600 seconds or 1 hour for execute again. Get-Date it's for mark the date and time when the code it's executed.
I don't understand if you need this or something else.
You can modify the line of Prog.exe with the code you need.
If you answer me i can help you.
Have a good day (:
