You need to select the one of the camera TV values from the pull down.  BULB is not accurate enough for fractions of seconds as it relies on Windows timers and for this reason you can only to whole seconds in bulb.  I don't thing there is a 1.8 seconds in-camera TV options though.

There is a similar request in the Feature Suggestion Box Forum for short exposures of arbitrary length, timed by the PC not the camera. The use case is for eclipse photography. It should be possible because other programs offer similar functionality.

Here is the post from the Suggestion Box:

I don't know about repeatability of very short exposures (eg < 1 second), but you should be able to use a high resolution timer (.NET Stopwatch class or the Win32 performance counters that are in kernel32.dll) for repeatable exposures of 1.8 seconds as has been requested. It is worth investigating and perhaps putting out as a pre-release feature to see what users think of it.
