I load time series using json files like so:

```auto
{
    "file-series-version": "1.0",
    "files": [
        {
            "name": "collision_dry_impulses_000040.vtu",
            "time": 0.1596
        },
        {
            "name": "collision_dry_impulses_000041.vtu",
            "time": 0.1636
        },
        {
            "name": "collision_dry_impulses_000042.vtu",
            "time": 0.1676
        },
}

```

Loading this time series file then has the first file in this list (`collision_dry_impulses_000040.vtu`) show during the time interval _time_=0…0.1596, i.e. **before** the specified time.

Is it possible to have every file show only **after** the provided time?

In my case this would result in no data being being loaded during _time_=0…0.1596.

Hi Bastian,  
Did you try to add an empty vtu file, i am not familiar with vtu file format, but it should possible to create one “empty” file, which with time 0.1596.

I was hoping for a solution that would not require tweaking the series file, but of course you’re right, I could include an “empty” file with a time \< 0.1596.
