Freedom Gundam statue at LaLaport Shanghai Jinqiao, photographed by 金琛玮 (Magdum Photo). Illustrative cover for the Gundam franchise.

Independent native-calendar view of Gundam Iron-Blooded Orphans · Post Disaster. Contains story spoilers.

The axis uses Post Disaster years. Moments retain their original story dates, source links, release context cards and visual plugins. There is no verified numerical conversion to Universal Century or Earth’s AD calendar in the sources used here.

Connection status

This setting is kept separate because no setting-specific shared-history or divergence link was established in the reviewed sources. That does not prove permanent disconnection: the 2014 Turn X manual uses a broad prospective Dark History framework, but predates this production and does not name it. Manual excerpt. The connected-histories comparison records the explicitly identified links; an approximate date is not enough to establish ancestry.

Moment details

Separate by tags

Events with any chosen tag move into a track above the rest of the timeline. Nothing is changed or saved.

Shift or scale times

Each time becomes (time − around) × scale + around + offset, exactly, as comparisons align timelines. A duration’s start or end that follows a moment moves with that moment.

        Your draft becomes a pull request. The upstream timeline stays unchanged until someone with write access merges it.

        Timeline plugins

        Plugin suites

        A suite adds several plugins at once. Plugins this timeline already has stay as they are.

        Create a suite

        Package this timeline's plugins to add them to other timelines at once. The suite carries each plugin's definition, custom plugins included.

        Plugins

        Plugin editor

        Define metadata fields and a restricted render script. No DOM, network, imports, loops or arbitrary calls. Later plugins override earlier effects. Installing takes effect immediately; publishing makes this version public in the server library.

        Plugin library

        Popularity counts public timelines with the plugin enabled.

        Compare timelines

        Select two to eight timelines visible to your account, or add a JSON file.

        Choose a shared time display

        These timelines use different printers or parsers. Choose the display for this comparison. Original times stay unchanged; use scale and offset to align different coordinate conventions.

        Timeline time display

        These settings belong to this timeline and are included in saved files and server copies. Times stay exact.

        Numeric labels are rounded. SI prefixes work best with unit symbols such as s. A Julian year is exactly 365.25 days.

        Displayed value = (stored time − origin) / scale. For Gregorian display, the displayed unit is one second from 1970-01-01T00:00:00Z.

        Preview uses the current window span and viewport width. Custom helpers: hasView(), viewLeft(), viewRight(), viewSpan(), viewWidth(), unitsPerPixel(), labelResolution(), purpose(). Existing printers and parsers can ignore this context.

        Servers

        The official server is https://timescale.info. You can connect to your own HTTPS servers too, and sign in to several at once: your timelines from each are listed together. Local .och files work without a connection.
