Blowing out a candle extinguishes the flame because it disrupts the balance of oxygen needed for combustion. When you blow on the flame, you remove the oxygen surrounding the wick, which is necessary for the flame to continue burning. This sudden lack of oxygen causes the flame to go out.
A wick works by absorbing the melted wax in a candle and drawing it up to the flame, where it vaporizes and burns, providing fuel for the flame to continue burning.
A candle wick works by absorbing the melted wax and drawing it up to the flame through capillary action. This process allows the wax to be continuously burned, sustaining the flame.
Candle wax is made of hydrocarbons that vaporize when heated by the flame. These vapors mix with oxygen in the air and ignite, creating a continuous supply of fuel for the flame to burn. The wax also acts as a wick, drawing the liquid wax up to the flame where it vaporizes and continues the burning process.
The wick in a candle draws up liquid wax through capillary action and vaporizes it when lit, creating a flame that burns the wax and produces light and heat.
Candle wicks work by drawing up melted wax through capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The wick then vaporizes the liquid wax, creating a steady flame that burns consistently.

A candle clock consists of markings along the length of a candle, with each marking representing a specific unit of time. As the candle burns, the wax melts and the flame moves down the candle. When the flame reaches a specific marking, it indicates that amount of time has passed. The rate at which the candle burns can be used to estimate the passage of time.

Heat from the flame melts the wax in the wick. As the melted wax vapourises, and is burnt, it is replaced by more melted wax travelling up the wick by capilliary action. As long as the flame remains, the process simply continues.
A candle-powered hot air balloon works by heating the air inside the balloon with a suspended candle flame. As the air inside the balloon is heated, it becomes less dense and rises, creating lift. The balloon will continue to rise until the air inside cools down or the flame is extinguished.
Either it has been extinguished, or it has burned down. Extinguishing a candle can be done by snuffing the candle, thus depriving the flame of oxygen, or by blowing it out. I am guessing you're more interested in the latter, so here goes, to the best of my ability. A flame is a byproduct of a chemical reaction, usually an oxidation process. Some element from the fuel, generally carbon, is combining with natural oxygen in the air. the flame is the heat and light energy given off by this reaction. As with all reactions, when one element runs out, the reaction ends. So in the case of snuffing the candle, the oxygen runs out, or in the case of a candle burning down, the fuel runs out, so there is nothing to combine with the oxygen, ending the reaction. Unless of course something else catches fire. Then you've got a bigger problem.
It cannot be used to tell the time of the day. It can only be used to tell the time interval that has passed. And if the flame is blown out, it doesn't work at all.
Relighting candles work by using a special chemical coating on the wick that can reignite after being blown out. This coating allows the candle to continue burning even after the flame has been extinguished.
When working with an open flame, always wear appropriate personal protective equipment, such as safety goggles and a lab coat. Work in a well-ventilated area, keep flammable materials away from the flame, and have a fire extinguisher or a fire blanket nearby in case of emergencies. Never leave the flame unattended and always extinguish it properly after use.
