Free time management and productivity tools for IT professionals

Productivity and time tools on it.you cover the time-related utilities that come up daily in software development and IT work: converting a Unix timestamp from a log file to a readable date, checking what time it is in Tokyo and Berlin simultaneously before scheduling a team call, running a Pomodoro session to stay focused during a long debugging session, or timing an on-call incident with a stopwatch. These aren't glamorous tools — they're the ones you use every day.

Every tool in this category runs entirely in your browser with no server communication. The World Clock, timers, and converters all use the browser's built-in APIs — the Intl.DateTimeFormat API for timezone handling and the Web Audio API for timer alerts. No data is stored, no account is needed.

Who uses these tools?

Developers
Convert Unix timestamps from API responses and log files to human-readable dates and back.
Remote teams
Check current time in multiple timezones simultaneously before scheduling standups and calls.
Sysadmins on-call
Time incidents with a stopwatch, run meeting timers during post-mortems, set countdown timers for deployment windows.
Anyone doing focused work
Use the Pomodoro timer for structured 25-minute focus blocks with automatic break intervals.

Key concepts

Unix timestamp (epoch) — The number of seconds elapsed since January 1, 1970, 00:00:00 UTC. The universal time representation in programming — compact, timezone-agnostic, and easy to calculate with.
UTC (Coordinated Universal Time) — The primary time standard by which the world regulates clocks. It does not observe daylight saving time. Server logs, databases, and APIs should always store times in UTC.
Timezone offset — The difference between a local time and UTC. For example, EST is UTC−5 in winter and UTC−4 (EDT) in summer. The IANA timezone database (e.g., America/New_York) handles DST transitions correctly.
Pomodoro Technique — A time management method using 25-minute focused work intervals (pomodoros) separated by 5-minute breaks. After 4 pomodoros, take a longer 15–30 minute break.
ISO 8601 — The international standard for date/time representation: YYYY-MM-DDTHH:MM:SSZ. The Z suffix means UTC. Always use ISO 8601 in APIs, logs, and data storage to avoid ambiguity.

Frequently asked questions

What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds since January 1, 1970, 00:00:00 UTC (the Unix epoch). It is the standard way to store and transmit time in programming because it is timezone-neutral and requires no parsing of date string formats.
Why does my timestamp differ by exactly 3600 seconds?
A difference of exactly 3600 seconds (1 hour) between two timestamps usually indicates a timezone offset error. Ensure all timestamps are in UTC before comparison.
What timezone should I use in my database?
Always store datetimes in UTC. Convert to the user's local timezone only at the presentation layer. This avoids daylight saving time bugs and makes database queries timezone-agnostic.
What is the Pomodoro Technique?
A time management method where you work for 25 focused minutes (one "pomodoro"), then take a 5-minute break. After four pomodoros, take a longer 15-30 minute break. The technique reduces mental fatigue and improves sustained focus.
How does the World Clock handle daylight saving time?
The World Clock uses the browser's Intl.DateTimeFormat API with IANA timezone identifiers (e.g., America/New_York). These automatically account for DST transitions, so the displayed offset is always correct for the current date.
