Old question, but for those looking for a solution now there is a system parameter available.

system.buildStartTime

You need to declare it in config (it's not available until runtime) in order to run. I set mine to value [Filled Automatically]

As you can guess, this time is set to the build start time, so that may not be ideal for some needs. But it's easy and reliable.
