The online world then took on a more recognizable form in 1990, when computer scientist Tim Berners-Lee invented the World Wide Web.
Here are some key dates for you to test your scripts: Epoch/Unix TimestampĪRPANET adopted TCP/IP on January 1, 1983, and from there researchers began to assemble the “network of networks” that became the modern Internet. Your second challenge is to work out and output an actual date in the DD/MM/YYYY HH:MM:SS format from an Epoch timestamp. You can test you script with today’s date and compare the output of your program with the Epoch date that appears at the top of this blog post.Įpoch Date to Human Readable Date Converter There are 30.44 days in a month (on average).To simplify your calculations you can make the following assumptions: To do so you will need to calculate the number of seconds elapsed between the date given and 00:00:00. DD/MM/YYYY HH:MM:SS as an input and output the date using the Epoch/Unix Timestamp. Your first challenge is to write a script, using a programming language of your choice, to convert a date entered in a human readable format e.g. Human Readable Date to Epoch Date Converter įor instance, the current date & time is: Note that a negative value would represent a date prior to. This explains how date & time values are actually stored on computers: using an integer value representing the number of seconds since 00:00:00 GMT. The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since Janu(midnight GMT).
