No, we're talking 1/60 second here.
A frame of interlaced video has even fields and odd fields. Both are encoded into one frame. If you are a moron and weave deinterlace something, then you will wind up with 30 combed frames per second. Blend deinterlacing is almost the same as weaving, but without the combing. Some people just discard half of the fields, which is gross-looking when there is motion. The proper way to deinterlace is to bob. If you bob deinterlace, even fields are picked, filled downward 1 line, and displayed for 1/60 second, and then the odd fields are picked, filled upward 1 line, and displayed for 1/60 second. You wind up with 60 progressive frames per second of half vertical detail, which the brain blends to look very close to full vertical detail, and motion is just as fluid as 720p60. The advantage of interlacing is that because fields are compressed to one frame, they share information, which makes for nice compressibility. You can interlace a 1080p24 movie to 1080i60 and lose nothing.

but was too late 
I just did it in the top of my post (so people know from the start
