Description

Clarifies timeout units in environment variable documentation. Users were confused whether OTEL_EXPORTER_OTLP_TIMEOUT=10 meant 10ms or 10s.

Added "(in seconds)" to documentation for:

  • OTEL_EXPORTER_OTLP_TIMEOUT
  • OTEL_EXPORTER_OTLP_TRACES_TIMEOUT
  • OTEL_EXPORTER_OTLP_METRICS_TIMEOUT
  • OTEL_EXPORTER_OTLP_LOGS_TIMEOUT
  • OTEL_EXPORTER_JAEGER_TIMEOUT (bonus fix for consistency)

Also added missing "Default: 10" to signal-specific timeout vars.

Fixes #4858
