The unix time stamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Therefore, the unix time stamp is merely the number of seconds between a particular date and the Unix Epoch. Europe Time Zones. Greenwich Mean Time (GMT). British Summer Time (BST). Western European Summer Time (WEST). Central European Summer Time (CEST). Eastern European Summer Time (EEST). London. Paris. Berlin. Athens. Warsaw. Kiev. Belarus. Moscow. Madrid. Stockholm. Amsterdam. Istanbul. The Time Zone Converter converts times instantly as you type. Convert between major world cities, countries and timezones in both directions.
Hi! 👋 It looks like your location is currently: Europe/Berlin
…where the local time is: 2021-05-07T13:23:25.595835+02:00
WorldTimeAPI is a simple web service which returns the local-time for a given timezone as either JSON or plain-text. Some additional information is provided, such as whether that timezone is currently in Daylight Savings Time, when DST starts and ends, the UTC offset, etc.
A full list of timezones can be found here, and further details about this service can be found in the FAQs.
Note: by default, the API returns JSON. Adding a suffix of
.txt to any API URL will return a plain-text response, which may be easier to parse on some systems.

1 Why PerlScript? Mostly as an interesting aside (something from a long-ago use case which serves now as a cautionary tale). TLDR, it's a bad idea. Still curious? Perhaps this topic on stack overflow would be of interest.
Roughly speaking, epoch is the time in seconds that have elapsed since computers starting counting. For our purposes we'll call that 0 hours, 0 minutes, 0 seconds starting from January 1, 1970. If interested in more info, I defer to this article about epoch definition.
Epoch is useful in computer programming because we can use it to compare dates mathematically which helps us write programming logic with it by converting a human-readable date format into its equivalent in epoch.

Er ok.. if you have a human friendly date/time that you want to convert, but you are shall we say 'tool averse' or you just enjoy mental gymnastics (good for you, btw), I'll take a stab at explaining a process for doing this manually.

You could do a rough calculation as follows:
For kicks and giggles let's use for our example a day that many folks will recognize, April 15, . And, we'll say it's 08:30 in the morning just to add some spice to this effort.
Eclipse oxygen version. Start with the year: . Subtract out 1970 from the year. - 1970 leaves us with years. (Sanity check)
Convert the years to days. So years multiplied by 365 days in each of those years. This gives us days.
Now the first relatively difficult issue--dealing with leap years. Like me, you may have had it explained to you that roughly every four years can be a leap year..with some caveats. Actually, (as a helpful individual has pointed out to me) the real rule is as follows: Years that are evenly divisible by 100 are not leap years, unless they are also evenly divisible by 400, in which case they are leap years, bringing the total number of days in that year to 366.
We need to examine each of the years between our target and the 1970 starting point. (This is one reason a tool is so great. You don't have to brute force the effort.) Writing a quick script to determine the calculation..
Want to sanity check whether a specific year is a leap year? (Uses algorithm in isLeapYear function code example above to calculate leap year.)
So, we need to add .
Now we need to factor in the months in the current year and convert to days. In our example, we're using April 15, so we have 15 days for the current month. January has 31 days, February has 28--unless this year is a leap year in which case it has 29. If this is a leap year, we caught it in our leap year check above. March has 31 days. Adding these up we get 15 + 31 + 28 + 31 = 105 days. Adding that back in to our running total of days we get
Now that we've got all of the days, let's convert those to seconds. It turns out that there are roughly 86,400 seconds in each day. (See the chart below for more useful conversions.) So we take and multiply it by 86400 to get seconds which have elapsed up until the beginning of April 15.

Now we need to factor in the hours and minutes that have passed in the current hypothetical day. It's 08:30. In each minute there are 60 seconds, in each hour there are 60 minutes, so we convert the 8 o'clock hour as 8 * 60 * 60. This gives us . Further, we'll convert the 30 minutes since the 8 o'clock hour into seconds, 30 * 60 which gives us . And we add those all back into the seconds so far to get
Lastly, we need to calculate our offset from GMT. Er, and then factor in daylight savings (ugh). In my case, PST, we're 8 hours different--and we participate in daylight savings. So I add (8 * 60 * 60) + (1 * 60 * 60) which gives , back into my running seconds to get my local time.
This should be the epoch time we're looking for. (See sanity checking your results below.) So, we're saying have elapsed since 1/1/1970--'0' in computer time. It's not very friendly from a human standpoint, but it's pure gold from a computer programming standpoint.
Plug back into the converter and see how far off March 15, 2006 you are. It's likely that you are off by some amount, probably the offset for your own local timezone. In general, you should always sanity check your results. Two good tests are, checking your results against today (using the current epoch from getTime/1000 for example), and '0' time. If your mechanism passes both tests, that's a good sign.
Of course, the most relevant question in all of this is 'why would I want to do any of this?' I've had the need for this arise many times. One notable example which occurred while working for a web hosting company was that we wanted to turn messaging chunks on/off 3 days after a new signup for services. We had a marketing manager that wanted to play some messaging to our audience of webmasters three days into their experience. Because there is a steady inflow of customers, the exercise is an ongoing one, and relative to each specific account. We needed a way to identify a member of the 3+ day audience and then some logic to trigger the messaging. In turning that need into programming routines, we did the following steps.
- First, we stored the epoch value of the date of each signup (for example, Jan 1, 2003 is 1041459471 in epoch). Now that the date value is an integer, we can do math with it.
- Second, we calculate 3 days in epoch measures (seconds) as follows.. (86400 * 3)
- Third, compare the current time with the signup time, plus the 3 days epoch value.

By making signup date a variable, this rule can apply to anyone for whom we want to know 3 days into the future of their signup.
1 Second = 1 in Epoch
1 Minute = 60 in Epoch
10 Minutes = 600 in Epoch
1 Hour = 3600 in Epoch
6 Hours = 21600 in Epoch
12 Hours = 43200 in Epoch
1 Day = 86400 in Epoch (24 Hours)
1 Week = 604800 in Epoch (7 Days / 168 Hours)
1 Month = (see below.. number of days in the month)
28 Days = 2419200 in Epoch (672 Hours)
29 Days = 2505600 in Epoch (696 Hours)
30 Days = 2592000 in Epoch (720 Hours)
31 Days = 2678400 in Epoch (744 Hours)
AVERAGE MONTHS IN YEAR = 2628000 in Epoch
(365 / 12 = 30.416666666666666666666666666667) (average months)
(30.416666666666666666666666666667 * 86400 = 2628000) (average months in Epoch)
1 Year = 31536000 in Epoch (365 days * 86400 seconds)
