Log for arcsynchro

How do I run the arcsynchro process to generate a log with a specific name?
If I run it as

arcsynchro.exe [parameter] > MyLogName.log

it will generate outputs without a timestamp. And if two arcsynchro processes are run (one manually and the other, e.g. when (re)starting the archive), which log will they write to?

arcsynchro run without parameters throws help, also contains:

/LOGDT - use log file ‘arcsynchro yyyy-mm-dd hh-mi-ss.log’

it is also in the documentation:
