This tool is used to convert the date from the unixtimestamp.app format into a human-readable date and vice versa. What is Unix time and what is it used for? To understand what it is used for, I will start with a general idea of what Unix time is. The Unix time (or Unix time stamp, which means ” time stamp” in Russian and has the same meaning) is the number of seconds since January 1, 1970. That is, the Unix TimeStamp at 01.01.1970 00:00:00 was 0. Two minutes later (120 seconds) Unix TimeStamp was 120. For example, 24 hours later (02.01.1970 00:00:00), the Unix TimeStamp already equaled 86400, as 60*60*24=86400 seconds passed. The Unix timestamp is already 1561815370 and the number is constantly growing because the seconds are constantly ticking.
But why use it? The point is that unixtimestamp.app is handy for storing and manipulating data in programming. I won’t go into details, but in short, the number is much more convenient to count and compare than a string with “left” characters. That is why most developers use the Unix timestamp to work with data in their projects, and in the database, we often see a very large number in the `date` field that does not look like a date at all. This is where this tool comes in handy. It helps you translate this “big number from the database” into human-readable data. And you can even do the reverse and turn any date into a Unix TimeStamp. That’s what this converter is capable of.
The Problem of 2038
As I said before, the number unixtimestamp.app is getting higher by 1 every second. Sooner or later this number will reach its limit and it will be in 2038. The thing is that the maximum number in the 32-bit operating systems widespread at the beginning of the 21st century is 2.31. This is the number that the Unix time stamp will reach in 2038.
And a solution to this problem has already been found. If you do not want your sites to stop counting time correctly in 2038, it is enough to use a 64-bit operating system on your hosting/VDS/dedicated server and not a 32-bit one. With the rapidly increasing power of computers and their decreasing cost, everything goes towards the fact that by 2038 the vast majority of website space services will be based on 64-bit OS. By the way, in a 64-bit system, this problem will not affect us for at least 292 billion years, which is quite enough to consider the problem of 2038 solved.
How to get Unix timePerl time
- PHP time()
- Ruby Time.now (or Time.new). To output: Time.now.to_i.
- Python import time first, then time.time()
- Java long epoch = System.currentTimeMillis()/1000;
- Microsoft .NET C# epoch = (DateTime.Now.ToUniversalTime().Ticks – 621355968000000000) / 10000000;
- VBScript/ASP DateDiff(“s”, “01/01/1970 00:00:00”, Now())
- Erlang calendar:datetime_to_gregorian_seconds(calendar:now_to_universal_time(now()))-719528*24*3600.
- MySQL SELECT unix_timestamp(now())
- PostgreSQL SELECT extract(epoch FROM now());
- SQL Server SELECT DATEDIFF(s, “1970-01-01 00:00:00”, GETUTCDATE())
- Unix/Linux date +%s
- Other OS Command line: perl -e “print time” (If Perl is installed on your system)
