Other mistake: When Michael climbs up the rope to get to the room below the infirmary, the rope is hanging from the manhole cover, but he still manages to lift the cover whilst hanging from it. In the next shot where he looks down the manhole, it's clear that there is nothing other than the rope he could have held on to while lifting the cover. An impressive accomplishment, defying the laws of gravity. (00:38:00)
Continuity mistake: When Kellerman orders Hale to give him his weapon, Kellerman pulls out his own weapon with his left hand. In the next shot, his gun is in his right hand, and he then transfers it back to his left. (00:36:45)
Revealing mistake: Michael climbs out of the hole during the escape in his coveralls. When he looks down to shout to the others to say it's clear he has no top on. The shot is reused from when he first climbed up. (00:37:10)
Visible crew/equipment: As the helicopter takes off at the start, the filming equipment is reflected. (00:02:00)
Answer: Roughly as follows. Linc "kills" Steadman in 2001. Michael robs the bank on March 9th 2005 and is sent to Fox River on April 11th. The breakout from Fox River takes place on or around May 25-31. Michael arrives in Sona on June 17th 2005. More details are here: https://prisonbreak.fandom.com/wiki/Prison_Break_timeline.

That wouldn't make sense because the original grave stone in series 4 has Michael's death date as 2005, which is supposed to be at least 3 years after Fox River.
