Class Method Details

.localize(value, zone_name) ⇒ Object

NULL-safe: localizes value (a UTC datetime) to zone_name, or returns it unshifted when there is no zone to localize to (nil value, blank/invalid zone name).

def self.localize(value, zone_name)
  return nil if value.nil?

  zone = zone_name.present? ? ActiveSupport::TimeZone[zone_name] : nil
  zone ? value.in_time_zone(zone) : value
end

.server_time_zone ⇒ Object

The deployment-wide IANA time zone identifier (ThecoreSettings ns: :main, key: :time_zone), or nil when unset — callers treat a nil zone as "leave the UTC value unshifted".
