In theory there is.
Using the GSV isntruction and reading the LocalDateTime object,
an array is returned as:
DINT[6] would be an equivalent to the free running clock

Consider using periodic tasks for code that you want to execute continuously on any particular interval. That is the prefered way of doing it and it offeres more flexibility as it does not lock you into a time base that is constrained to time slices of 2 x 2x milli-seconds
However, if you absolutely must have a free running clock equivalant you can create your own with any timer and using the bits of the timer accumulator - FreeRunningClock.Acc.0 through FreeRunningClock.ACC.30. Make the timer preset 2147483647. FreeRunningClock.ACC.31 won't be availalbe because it would normally be the sign bit and a timer Acc can never be negative.

I use this method.

GSV Reads the data (WALLCLOCKTIME) and use SSV to set it.

Here is a sample of what we do
Our tag, Time[0], is an array of 7 Dints.

Dang, I'm not very good at the interweb. I had a pic in here at one point, I even previewed it to make sure it worked. Now my work is banning me from photobucket, so I can't fix it.
To add to what Mike said, the Attribute needs to be "DATETIME" in version 15 or below and "LocalDateTime" in version 16.

Time for the sledge hammer. Why did AB change the #&$@#^ Attribute name? I haven't upgraded to V16 (working on two projects and didn't want to hose anything up) yet. My rep told me that 17 is coming... 16 just got here. <insert standard complaint about retarded software pricing and upgrade policies here>
