i always put 1, since the 1 its by defaultMr. Hotshot, conduct a test yourself.
on your status window while being offline.
/play -s <file> 1
- Playing 'file' to Status Window with 1ms delay <= this is not a one second delay but 0.001. All the messages in the file will then spit out all together, literally without a delay.
/play -s <file> 1000
- Playing 'file' to Status Window with 1000ms delay<= this equals to one second. And you will see all the messages come out one line after another in a one second delay.
By default, the delay is already 1 second; you do not need to include 1000.
