I have a situation, where we input ages. The application is for older people. therefore, it might happen that some one is older and his date of birthe is 1899 or 1892 etc. He will definately a lucky guy having this much long age. But what i ahve come to know that PHP has a limitation of backward timpstamp. That is t cant go beyond 1900.

I am using mktime() function, so is there any way out to this ?
