Module: Clowk::Phlex::Charts::WebTime

Defined in:
lib/clowk/phlex/charts/web_time.rb

Overview

WebTime — the single "render this moment in the app's timezone" seam for the chart x-axis + tooltips. Uses ActiveSupport's Time.zone when present (Rails hosts), else falls back to UTC — so the lib works with or without Rails, and a host can retune the zone in one place later.

Class Method Details

.strftime(time, pattern) ⇒ Object

strftime — format a moment (Time / TimeWithZone). Never raises: returns nil on bad input so views render "—" instead of 500-ing.
