inconsistent timestamp intervals in prime.log

[ixfd64]

Not sure whether this is an issue, but I noticed that the timestamp intervals are sometimes inconsistent when Prime95 updates the log file. At first I thought the interval was 300 seconds, like in the case of the results file. However, sometimes Prime95 writes a new timestamp even when the previous entry was added just seconds earlier:

[Fri Jun 21 19:22:37 2019 - ver 29.8]
Exchanging program options with server
[Fri Jun 21 19:22:54 2019 - ver 29.8]
Exchanging program options with server

I've also seen Prime95 add entries under the same timestamp even though the previous one was written more than five minutes ago:

In this particular case, the results were reported over 30 minutes apart:

Is there a reason for this?

I noticed that Prime95 version 30.3 behaves the same way on Windows. So this is probably intentional.
