add start time of process in process status

[ktoy]

In addition to the uptime of the process, how about showing the start time as well?

Sounds good, but the behaviour may be tricky:

1.) if we'll record the start time at some given point in time, and the clock will be adjusted for example by NTP (time jump) after that, the start time may look weird (e.g. 1.1.1970).

2.) if we'll can simply subtract uptime (which we record already) from the current time, the result may be also flawed, as the time may jump forward/backward, depending on the system clock error
