Unixtime format is not working on windows

[intx82]

Unixtime format specified via command line arguments is not working on Windows, but works well on Unix.

C:\Program Files\mosquitto>mosquitto_sub -h host -t /# -F "%U %t %p"  //<- exited after start

C:\Program Files\mosquitto>mosquitto_sub -h host -t /# -v //<- Works well

Thank you for this report. Unfortunately Unix timestamps aren't supported by the Windows version of strftime. That function was producing an error when you tried it, hence the immediate exit. I've changed it so a message is printed to make it obvious what is going on at least.

Okay, thanks, you can close the issue.
I have found another solution:

mosquitto_sub -h host -t /# -v -F "%t %p" | perl d:/wrk/tools/moreutils/ts "[%s]"
