CLUSTER TERMINAL-ACROSS-TIME · 7 ENTRIES · EARLIEST ENTRY 2026-04-03

Terminal timezone coordination tools

This cluster comprises terminal-based utilities for visualizing and comparing time zones, including a world-clock app with day/night maps and 24-hour timelines, a visual time-zone comparison tool, and a command-line manager for system timezone settings. The dated history is too thin to read a shape from, as only one dated entry exists before the index start, so the cluster's timeline predates the index or its members are undated. Among members with traction signals, terrahour leads with 79 stars, followed by tz-injector (1 star) and zonetimeline-bin (0 stars).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
