I guess your best bet is to find out the "off-peak" timing for your server and just do a quick 10minute login to create it.

I did likewise when I started off at Tonberry. Had to just do a crazy early wake up just for 1 day around 6am at my time just to create it. But it's worth the trouble since that's the only time you'll ever need to be on at those timings (unless you work shift hours at your job or something)
