Yes.

Post links to where you bought the shields so we can check if there are conflicts between the pins used by each shield.

Most Ethernet shields have an SD slot included.

The Ethernet Shield uses pin 10 as CS for the W5100 Ethernet controller. It uses pin 4 as CS for the SD slot.

The Data Logger Shield uses pin 10 as CS for the SD slot.

So you can't use the SD slot on the Data Logger Shield and the W5100 on the Ethernet Shield at the same time without rerouting pin 10 on one of the shields. Fortunately, the Ethernet Shield has its own SD card slot. I believe that as long as you don't put an SD card in the slot on the Data Logger Shield, it won't cause any interference with the W5100.

I guess you only want to use the Data Logger Shield for the RTC. There is no conflict between the pins used by the RTC (20 and 21 on your Mega) and the pins used by the Ethernet Shield, so you should be able to do this.
