Claude System Time — Productivity skill for Claude Code

system-time

A Claude Code plugin that gives Claude the **real** current date, time, and timezone from the system clock, instead of guessing from its training cutoff.

What it does

Piece	Behavior
SessionStart hook	Injects local time, timezone, ISO 8601, UTC, and epoch at session start.
UserPromptSubmit hook	Re-injects the time, throttled to once every 5 minutes, so long sessions stay accurate.
/time command	Prints the current date/time on demand. Takes free-form arguments, e.g. /time in Tokyo.
current-time skill	Teaches Claude to read the clock for date math, timezone conversion, and timestamps.

Install

Copy or symlink this directory into your plugins directory, then enable it:

claude plugin install system-time

Or, for a local checkout, add a marketplace entry pointing at the parent directory and install from there.

Configuration

`SYSTEM_TIME_THROTTLE` — seconds between per-prompt time injections. Default `300`. Set to `0` to inject on every prompt.

export SYSTEM_TIME_THROTTLE=0
