Negative time on Timed Security Chest in Delta Zone

[Shadow Sovereign]

So I'm trying to complete all the achievements, and one of the simplest I'm after is opening a timed security chest, however when I reach it, it usually only takes me about twenty seconds to find it, it reads -8:50 or something like that, which obviously doesn't allow me to open it.

You need to find it before the clock strikes 10 minutes. Most easily done on Drizzle. The negative value shows how much time you missed it by, up to 9 minutes and 59 seconds.

But it's like that twenty or thirty seconds after I reach it

As fluffyfren said "You need to find it before the clock strikes 10 minutes" that is you have 10m to clear the previous stages, find the box and open it not 10m to find the box after entering the stage
