Alarm?

[RiversideGuy]

Must be missing something, tried to set an Alarm (timed nodes ya know!), set for Eorzea time with a 30 min advance notice... set it for repeat, the 30 min warning didn't happen, nor the time as I had set it. Bummed.

I remember having trouble getting it to work as well, but I don't remember the exact thing I did to get it to work. When I get home I'll update you with how to do it if some kindly stranger hasn't helped already.

I wasn't aware it worked on Eorzea time. I've really only used it in real time for reminders for things like reapplying food, squadrons, feeding chocobo and what not.

Never really used the alarm system, so I tested it a few times. A few things I've noticed:

-Reminder (Minutes) uses normal minutes, even if you have Eorzea Time selected as Clock Type.
-If you have a Reminder set, that's the only time when the Alarm will sound. Without a Reminder set, the Alarm will sound at the exact time you've set.
-The Alarm is part of System Sounds, so make sure to not have that one disabled in the system config.

-Reminder (Minutes) uses normal minutes, even if you have Eorzea Time selected as Clock Type.

This is definitely what messed up OP's alarm reminder. Set a reminder time of 1 or 2 to sound the alarm ~21 or ~41 Eorzea minutes before the node pops. A reminder time of 30 is about 10h 17min Eorzea time.
