You have to wait for the photo to totally load. Then place your cursor at the top of the photo. You will notice it is 6:10 PM. Bring the mouse down slowly over the photo without pressing the button on the mouse. Do not right or left click. Night time appears, and the lights come on .... At 7:40pm, its dark! Photo Technology at its best!
If you hover at the top of the photo and slowly move your mouse straight down across the photo it will go from early morning to late night... should be able to pull it off with flash as mentioned above. Looks like more than 2 pics but on close inspection not much changes other than the lighting and the boats dissolve on the last pic...
The flash widget you move up and down changes the opacity of the top image making it seem to be a time lapse sequence you control. The widget measures the distance to the top of the frame, divides it into the total distance top to bottom giving a %age less than one and applies that %age as an opacity control.
There is also a semi-transparent coloured panel over the top of the whole thing. As you move the mouse down the colour changes from a light blue tint to a brownish-red and then to deep blue-grey.
Beneath that it looks like the daytime image fades revealing the night image underneath.
Looks like only one image. The boats did not move and are at the same position. Must be some effect applied on the same image though the lights look so real (I know it as I live there...)

There is more than one image in use here. There are two (no five) (NO SIX!) boats that dissolve. Very clever concept though.
Another give-away that it's only 2 images is that the pattern of lights on the tower doesn't change at all, they just fade in and out. Also, someone said was from early morning to evening; not so... it's from early evening to night time, the time laspe appears to be an hour and a half or so between the 2 images.
it's simple to make the pictures. By looking at the pic it seems to be divided into about 20 bands or so where each band has a higher opacity than the last meaning the change is gradual.
To make the pictures is easy: take a pic at 6am and take it again at 6pm. Take the late pic and save 1 file at 5%, 1 file at 10% opacity and so forth. Then all the flash thing does is scroll between the pics.
