			guoyunheAuthorUnsubmitted Not Done `date` is optional, so if it not found, just leave it as undefined. I can add some detection to `toString()` function, in case they passed some non-string args. `mach()` should be safe. guoyunhe: `date` is optional, so if it not found, just leave it as undefined.
