Probably not. To make him appear in the bar, you open the Console (F12 or CTRL + Shift + J) you can type in
flags['KASE_TIMER'] = Time Passed in minutes (Minutes + (Hours * 60) + (Days * 1440))
Alternatively, you could Save to File, post it here and ask someone to edit it for you.
For future reference, the timer doesn't start until you talk to him in the bar for the first time, so you can delay his departure indefinitely.
