Your time of birth is very important when making a horoscope chart. Astrologers require a person’s birth time to cast charts accurately. The planets are constantly moving around and switching from aspect to aspect, so the difference of an hour can affect your birth chart, Moon sign and Rising sign and this will lead to affect who you are.
Not everybody knows the time at which they were born, you can find your birth time information from your birth certificate or by asking your parents, but still you don't know what your actual time of birth was, then a guesstimate can be something is better than nothing. It’s not the actual time though.
If someone’s birth time is unknown, then a chart can still be cast with the help of guesstimate. Most astrologers will use 06.00 or 12.00 as a good place to start. People born during this time window have outstanding levels of ambition and can be stubborn while chasing a goal. These people have strong bonds with their mother.
Every 4 minutes another level of a specific zodiac sign shows up on the ascendant, (eastern skyline) and therefore an inverse sign new degree shows up on the decendant (western skyline), and no doubt the midheaven (straight up) and the nadir (straight down), and this might roll out sign improvements on a few or the various eight horoscope house signs - relying significantly upon the scope of the origin.

Now and again a brief birth-time mistake could really make the ascendant another sign and conceivably cause other significant horoscopic changes.
An off-base birth time could bring about the accompanying conceivable horoscope mistakes: An alternate ascendant (rising sign) - or an alternate decan of a similar sign, and an alternate relative (seventh-house sign/ruler) - or an alternate decan of a similar sign; distinctive midheaven and nadir signs, various signs on a few or every single other house; most assuredly, a right birth time is absolutely critical for a legitimate and beneficial natal horoscope perusing.
