TOTP generation does not handle 3 settings (TrayTOTP 'time sync')

[nta]

TrayTOTP for KeePass (.NET) on desktop systems might sometimes store formats such as 30;6;https://www.google.com/ in TOTP Settings, with the intent to use the Date header from a HTTP query as a source for a time delta. Currently, in KeePassium, these entries seem to be skipped entirely, and treated as if there's no TOTP.

KeePassium/KeePassiumLib/KeePassiumLib/db/totp/TOTPGenerator.swift

Lines 106 to 109 in be35b22

	guard settings.count == 2 else {
	Diag.warning("Unexpected TOTP settings number [expected: 2, got: \(settings.count)]")
	return nil
	}

Keepass2Android, for example, does not implement this, but shows a warning instead when viewing one of these entries notifying the user that, indeed, time correction is not implemented:

I'll get this fixed, thanks!

It is tempting to implement this properly, with actual network requests. However, I am not sure whether arbitrary network requests would be an acceptable behavior for KeePassium... Will probably just ignore the URL parameter for now...
