Assuming you are not reading a foreign language, the eyes usually follow a general left to right path and rest on the left side of the screen. Hence any subtle change in the data located on the right side of the table would be overlooked.
Rearranging the Column
Based on your screenshot, it appears that your static data resides on the left side of the table and the dynamic ones are on the right. Have you tested this on a smaller screen device? Do you have to scroll to the right to view the dynamic data?
If the order of the column is not important, you might want to consider rearranging the column and moving the dynamic data closer to the left of the table.
Animating the Data Cell
Just to add on what @Raphaelle has proposed on using animation. If the data updates instantly, you might want to animate the background colour of the data cell instead. Flash and fade out a different colour (e.g. yellow) on the data cell. This would draw their focus to the part that has changed. This should do the trick.
Move the Datepicker
Alternatively you could adopt a more drastic approach by changing the table layout:
