I need support for scale typeutc. It is very common to store/process dates in UTC time (Unix epochs).

Describe the solution you'd like
Support forutc scalelike Observable Plot.

Describe alternatives you've considered

• Observable Plot
• Transform Unix timestamps (UTC) to conform to local time scale?

Additional context

• I thought I would try porting my Observable Plot plots to SveltePlot, but lack of UTC support may be a dealbreaker...

An error occurs when I try to portthis code:

const plotOptions = $derived({width: clientWidth,height,marginRight: MARGIN_RIGHT,marginLeft: MARGIN_LEFT,marginTop: 0,marginBottom: 0,y: { axis: null, domain: [yDomainTop, yDomainBottom], range: [0, height] },x: {type: 'utc',axis: xAxis ? true : null,domain: [msStart, msEnd],range: [MARGIN_LEFT, clientWidth - MARGIN_RIGHT],tickFormat: (ms: number) => nsWeatherData.tzFormat(ms, 'ha'),},});

No errors usingtime type scale, but the resulting days are misaligned:

• 12am June 16 should start at the very left.
• The cursor is currently over Jun 16 1am, but SveltePlot axis shows 11am June 15.
• (Showing KST data from CST timezone)
