timestampOffset property
Only applies to outputs that support program-date-time stamp. Use Timestamp offset (TimestampOffset) to overwrite the timecode date without affecting the time and frame number. Provide the new date as a string in the format "yyyy-mm-dd". To use Time stamp offset, you must also enable Insert program-date-time (InsertProgramDateTime) in the output settings. For example, if the date part of your timecodes is 2002-1-25 and you want to change it to one year later, set Timestamp offset (TimestampOffset) to 2003-1-25.
Implementation
final String? timestampOffset;
