Ejemplos de Timestamp API

// Express.js endpoint
app.get('/api/timestamp/current', (req, res) => {
  const timestamp = {
    unix: Math.floor(Date.now() / 1000),
    unixMs: Date.now(),
    iso: new Date().toISOString(),
    utc: new Date().toUTCString(),
    local: new Date().toString()
  };
  
  res.json({
    success: true,
    data: timestamp,
    generatedAt: new Date().toISOString()
  });
});

// Response example:
{
  "success": true,
  "data": {
    "unix": 1640995200,
    "unixMs": 1640995200000,
    "iso": "2022-01-01T00:00:00.000Z",
    "utc": "Sat, 01 Jan 2022 00:00:00 GMT",
    "local": "Fri Dec 31 2021 16:00:00 GMT-0800 (PST)"
  },
  "generatedAt": "2022-01-01T00:00:00.000Z"
}

Get current timestamp in multiple formats

// Express.js conversion endpoint
app.post('/api/timestamp/convert', (req, res) => {
  const { timestamp, from, to } = req.body;
  
  try {
    let date;
    
    // Parse input based on format
    if (from === 'unix') {
      date = new Date(timestamp * 1000);
    } else if (from === 'unixMs') {
      date = new Date(timestamp);
    } else if (from === 'iso') {
      date = new Date(timestamp);
    }
    
    // Convert to target format
    let result;
    switch (to) {
      case 'unix':
        result = Math.floor(date.getTime() / 1000);
        break;
      case 'unixMs':
        result = date.getTime();
        break;
      case 'iso':
        result = date.toISOString();
        break;
      case 'utc':
        result = date.toUTCString();
        break;
      default:
        result = date.toString();
    }
    
    res.json({
      success: true,
      input: { timestamp, from, to },
      result: result,
      convertedAt: new Date().toISOString()
    });
  } catch (error) {
    res.status(400).json({
      success: false,
      error: 'Invalid timestamp format',
      message: error.message
    });
  }
});

Convert between different timestamp formats

// Express.js timezone conversion
app.post('/api/timestamp/timezone', (req, res) => {
  const { timestamp, fromTz, toTz } = req.body;
  
  try {
    const date = new Date(timestamp);
    
    // Convert to target timezone
    const options = {
      timeZone: toTz,
      year: 'numeric',
      month: '2-digit',
      day: '2-digit',
      hour: '2-digit',
      minute: '2-digit',
      second: '2-digit',
      hour12: false
    };
    
    const converted = date.toLocaleString('en-CA', options);
    const isoConverted = new Date(converted + 'Z').toISOString();
    
    res.json({
      success: true,
      input: {
        timestamp,
        fromTz: fromTz || 'UTC',
        toTz
      },
      result: {
        formatted: converted,
        iso: isoConverted,
        unix: Math.floor(new Date(converted).getTime() / 1000)
      }
    });
  } catch (error) {
    res.status(400).json({
      success: false,
      error: 'Invalid timezone or timestamp',
      message: error.message
    });
  }
});

Convert timestamps between different timezones
