Validate vendor-specific timestamp semantics — validate_vendor_timestamp

The audit records expected semantics rather than silently coercing clocks. Tobii data can carry device/system timing; Pupil Labs Neon timestamps are high-resolution UTC nanoseconds in native recordings; Gazepoint may expose native monotonic and media-relative clocks depending on export type.

Usage

validate_vendor_timestamp_semantics(
  data,
  vendor,
  device_time = NULL,
  system_time = NULL,
  media_time = NULL
)

Arguments

data: Input data frame or compatible tabular object.
vendor: Vendor identifier.
device_time: Device timestamp column.
system_time: System timestamp column.
media_time: Media/stimulus timestamp column.
