DevClock

Convert timestamps across configurable timezones and generate copy-ready log query windows for Splunk, Grafana, and CloudWatch.

DevClock is a developer tool for engineers who work across timezones and need to quickly convert timestamps from logs, screenshots, and monitoring tools into their local time. FEATURES → Smart Timestamp Input Paste anything — Unix epoch, ISO 8601, syslog format, Apache CLF, or plain natural language like "yesterday 4pm" or "2 hours ago". DevClock figures out the format automatically. → Source Timezone Toggles Timestamps in screenshots often have no timezone context. Instantly re-interpret any time as US/Eastern, UTC, UK/London, or your local timezone with one click. → Log Query Builder Generate copy-ready search fragments for Splunk, Grafana, and CloudWatch with a built-in ±1 minute window around your converted time. Paste directly into your query bar. → Configurable Set your default target timezone, customise which timezones appear as quick toggles, choose your query provider, and switch between 12 and 24 hour display formats. → Privacy First Runs entirely in your browser. No data is collected, transmitted, or stored outside your own machine. All processing is local. BUILT FOR Engineers debugging production incidents across US, UK, and Australia/Melbourne timezones. Works great alongside Splunk, Grafana, CloudWatch, Datadog, and any log tool that accepts ISO 8601 timestamps.
