Please add a switch to generate archive name YYYYMMDDHHMMSS using the current date and time

ex.

archiveYYYYMMDDHHMMSS.7z
archive20230601012543.7z

That's indeed very useful, but I doubt it should be added to the core program. Assuming we're talking about the command line, why not create a function/alias in your terminal of choice? For example, in Windows/PowerShell I have a Get-FileNameSafeTimestamp function aliased to fst that returns exactly that. So, typing 7z.exe a "archive-$(fst).7z" * will add all current files to archive-20230602T1059340252.7z. My implementation is:

# Timestamp in filename-safe format.
function Get-FileNameSafeTimestamp ([switch]$Utc, [switch]$DateOnly) {
    $fmt = 'FileDate'
    if (-not $DateOnly) { $fmt += 'Time' }
    if ($Utc) { $fmt += 'Universal' }
    Get-Date -Format $fmt
}

Not to mention that this way also makes it available to any program. :)
