Yes and you can use about anything as a sun dial as long as it is stationary. Mark the ground from day to day to mark each day, and of course it would not be effective on cloudy days.

Why can't you tell the time on a sundial all year long?
You need direct sunlight to use a sundial, so it cannot be used at night or when clouds or pollution are diffusing the sunlight too much to create shadows.

How do you install a standard sundial in the Southern hemisphere?
There is no such thing as a standard sundial. For every different latitude (degrees north or south) the gnomon (the triangular shadow making bit) has to be cut differently. If you live 30 degrees south, cut the gnomon to a 30 degree angle. Set up the sundial so the sharp end of the gnomon is pointing exactly North. The easiest way is to just twist the assembled sundial until it shows the right time. If you want to be as accurate as possible you need to take longitude and time of year into consideration as well, but as most sundials are simply ornaments, that detail is not given.
Are sundials one hour slower in summer due to gmt?
Sundials are one hour slower in the summer in places that use Daylight Saving Time. They aren't slower 'due to GMT'. GMT, or standard Universal Time, (UCT, I believe) remains the same all year regardless of where you are; GMT is not adjusted for Daylight Saving Time. You could, of course, turn your sundial to adjust for Daylight Saving Time, but if you are that interested in accurate time, you probably would not rely on a sundial.
Does a sundial change everyday?
The sundial itself doesn't really change day to day, or even year to year. They are generally fixed to the Earth and are not, in general, portable. The shadow cast by the "gnomon" (the pointer of the sundial) does move moment by moment throughout the day, and slightly from day to day.

What did the ancient egyptians invent to keep track of records?
They invented the 365-day calendar. They used the Sun to keep track of the days throughout the years. They divided the year into 3 seasons of 4 months. Each month had 30 days. Their year had 360 days. The ancient Egyptians also used shadow clocks. The first ones were obelisks. The moving shadows formed a kind of sundial to help tell time. The sundial was then used very often since.
Why is sundial not completely reliable?
A sundial is not completely reliable because of the angle of the sun toward the earth at certain times of the year. It is also not perfectly reliable because of cloud covering that can obscure the readings.
