I find it very usefull that there is a validation that the departure time is checked against the minimum period a flightplan shall be files in advance. But I think this validation shall be able to be overwritten. There are case either ATC does not stick to the minimum advance period or even requests a flightplan with a departure time of let‘s say 10 minutes from now.

In the very same context it should also be possible to amend the departure time not only to a delay but also to an earlier departure time.

These two suggestion are based on the needs of a today‘s flight from Innsbruck to Venice and back (btw: very nice trip).

What do you think?

I tried it on Saturday in Austria and again on my return flight from Venice in Italy (everytime connected via 4G from my iPad being present in the country of origin - don't know if this has impact). I do not remember the the exact phrasing but when entering a departure time it does not allowed me to proceed, and the message was something like this "departure time to close ahead". 
When trying to file in Venice I was at the waterbus heading to the lido island at 5:01pm and I tryed to file a departure time 6pm (repective 4pmZ) and got rejected. The earliest time allowed to be filed was 4:15pmZ. I tryed to reproduce this today and surprisingly it let me file everything later than 5min in advance (Today my iPad is connected via WLAN to my German DSL line). Very strange.
