![]() Unix timestamps and therefore the need to convert to and from epoch time and human readable dates and times are widely used in databases (MySQL, Oracle, PostgreSQL, SQL Server) and various programming languages such as C++, C#, PHP, Python, JavaScript, Ruby, Perl, Java, R, and more. Epoch, also known as Unix timestamps, is the number of seconds (not milliseconds) that have elapsed since 00:00:00 GMT. Every day in Unix time contains exactly 86400 seconds meaning that no seconds are being added to or subtracted from the day as a result of positive or negative leap seconds. Unix time is not adhering to UTC due to how leap seconds are handled. The Unix epoch is 00:00:00 UTC on 1 January 1970 and is defined as such in relation to the fact that the Unix operating system it was first used on was invented just a few months prior in 1969. A Unix timestamp is simply the number of seconds that have elapsed since the Unix epoch, excluding leap seconds. It is often referred to as "Unix timestamp", "Epoch time", "Posix time" in technical documentation and slang. In computing, Unix time is a system for uniquely describing a point in time with an accuracy of up to a second, though some systems may extend that to a millisecond (e.g. The same applies in case of specifying the minutes without entering seconds. ![]() Likewise, entering an hour without specifying minutes and seconds assumes the beginning of that hour.Similarly, a Unix year is ¼ day longer than the calendar year to account for 1 leap day every 4 years. Entering a full date without any time will output the Unix epoch timestamp for midnight on that date (00:00 AM). 1 Month: 2,629,743 seconds (30.44 days on average) 1 Year: 31,556,926 seconds (365.24 days) You’ll notice that months are averaged out to account for the different number of days.Entering a year and a month, such as "2023" and "2" (February) will output the timestamp for " 00:00:00", meaning midnight on the first of February, 2023.Entering just a year, such as "2023" will output the timestamp for " 00:00:00", meaning midnight on the first of January, 2023.To use the tool in timestamp to date mode, just enter a Unix timestamp and it will automatically be converted to a GMT / UTC date and time string as well as a string based on your locale, including your current timezone as reported by your browser.Īlternatively, use the converter in date to timestamp mode by entering either a fully qualified date and time or a partial one. The unix timestamp now is (updates automatically):Ĭonverted to date and time this is Sat, 02:07:56 GMT which is often also expressed as 02:07:56 GMT in computing.
