In the beginning of the episode, when Jack is briefing Tony on the phone, he mentions the time "10:15 p.m." , however near the end of the previous episode, after a fight, when Jack checks the cellphone, it states "22:30".
At the end of the previous episode, Senator Mayer is seen leaning dead against the wall in an almost sitting position. At the beginning of this episode, he is flat on his back with evidence number cards around his body. In any murder investigation, the police would never move a body from its resting position, especially while the site investigation continues.
At the end, when Jack is standing in front of the truck, gas can be seen flowing away from the truck. However, the biological weapon that was releasing the gas had been taken away from the truck in a previous shot.
To the poster of the above. The 2230 on the text message means that will be the time at the port of Alexandria to meet, not the present time. Older flip phones like that do not display present time in text message mode.
