With this browser-based application, you can create an increasing or decreasing list of UNIX timestamps. You can specify the starting timestamp or the starting calendar date and generate a specific count of timestamps in the list. You can set the interval between the timestamps and add fuzzing to the intervals so that they have unequal lengths. You can also set a custom separator for the timestamps and display human-readable time next to them. Created by computer nerds from team Browserling.

This is a quick online utility for creating a UNIX Epoch time sequence. UNIX Epoch time (also known as UNIX timestamp or POSIX time) is a convenient way to represent a calendar date and clock time using a single integer rather than a bunch of date and time components (years, months, days, hours, minutes, seconds). To create a sequence or a list of timestamps, in the options of this utility, you can specify the beginning date and time of the sequence by entering a timestamp or entering a calendar date. For example, if the start date of the list equals "2025-01-01 00:00:00", then it's the same as the timestamp "1735689600". The output UNIX time list can consist of any number of ascending or descending timestamps. If you want the sequence to increase, select the "Increasing Timestamps" mode. If you want it to decrease, select the "Decreasing Timestamps" mode. In the options, you'll also find a field to set the number of items in the output and a field to set the time interval between them. For example, you can generate 3 ascending timestamps 5 days apart and get a list "1735689600, 1735257600, 1734825600". You can also randomize the difference between the timestamps a little bit by specifying the fuzzy interval option. For example, if the main interval is 5 days and the fuzzy interval is 1 day, then the difference between the timestamps will be 5±1 days, which means the difference can range anywhere between 4 and 6 days. To make it clear what the real date hidden behind the timestamp is, you can activate the option to print human dates. With this option active, you'll get the usual calendar dates in "YYYY-MM-DD hh:mm:ss" format in parentheses next to each UNIX timestamp. Additionally, you can also set the timestamp separator character in the options. For example, to place them in a column use the "\n" separator; or to get a line of timestamps using any other separator, such as a comma or a semicolon. Timeabulous!

In this example, we create a comma-separated sequence of ascending UNIX timestamps from the 21st-century. We start it from the timestamp "946684800" (which equals the date "2000-01-01 00:00:00") and generate 21 incremental UNIX times with a difference of 5 years. The interval between the first and the last timestamp is 3155760000 seconds, which equals 100 years.
In this example, we create a list of negative timestamps that goes backward from the beginning of the UNIX Epoch. Negative timestamps do not mean negative dates. If we look at the definition of the zero timestamp, then it equals the date "1970-01-01 00:00:00", and all earlier dates have a negative timestamp. We start the sequence with the zero timestamp and decrease each subsequent value by "10 months 10 days" with a deviation of 3 days, which means that the number of days in the intervals can be 7, 8, 9, 10, 11, 12, or 13 days. We create a column of 12 timestamps and also print human time next to them to show you that only the timestamps are negative but the dates are not.
In this example, we display a countdown to the Year 2038 bug. The Y2038 bug is well-known because at 03:14:07 UTC on 19 January 2038, UNIX time will reach the last possible value that fits in a signed 32-bit integer. All timestamps following the Epochalypse can only be generated by computer systems that do 64-bit arithmetic. We start our list at "2038-01-19 03:14:00" and increment each value by 1 second until we reach the critical value of 03:14:07.
