In the 30th minute Detective Ben reads from a transcript that Danny left on November 17th to fire someone, which (as he mentions) was the Tuesday before. This (or the day after that) is supposed to be the date of the incident this movie is about. However, when at the beginning of the movie Danny's brother Tony is looking at his phone to read the message Danny assumingly sent him during or right before the mentioned incident the date says: Wednesday March 11th.
