I upgrade a 7.9.12 application to 8.0.7 nigthly

```auto
value = 10
eqtPath = "...."
system.tag.writeSynchronous("%s/TR/ADMPORTS" % eqtPath,value,5)

```

system.tag.writeSynchronous trigger some Timeout error in 8.0.7  
I suspect 5, which mean 5 second en 7.9 is not converted to 5000ms for the timeout of system.tag.writeBlocking used in 8.0

In 8.0.7, if I change the function to:

```auto
value = 10
eqtPath = "...."
system.tag.writeBlocking(["%s/TR/ADMPORTS" % eqtPath],[value],5000)

```

I don’t have any timeout.

Yep, looks like that’s what is happening. Should only cause problems with writes from the client.

Actually as far as I can tell this is documented and implemented as milliseconds everywhere except when the `writeSynchronous` comes from the client, where the bug is actually that in that scope it’s treated as seconds in 7.9.
