in this competitve day and age its still good to get as much jet time as and when you can;
I'm not sure what you think this mythical 'jet time' will do for you. For a start, it's not jet time, it's simulator time. As you don't hold a rating on the aircraft type, and nor are you being instructed in order to gain a rating, I'm pretty sure you can't claim anything for the sim time you achieve. It is purely a training tool. Othere than the fact that it gives the atmosphere of a flight, and imparts a useful amount of tension due to you not knowing much about the represented aircraft, you could do the course on two chairs in a classroom!
The only reason companies use modern aircraft simulators is that they can charge you disproportionately more money for them. No employer gives a damn whether you did your MCC in an A320 sim or a Lancaster sim!
