What is the global fee period?

Could you please clarify what you mean by "global fee period"? Is this referring to a specific timeframe for paying fees related to cryptocurrency transactions, or perhaps a more general concept in the world of finance? It's not a commonly used term in my field, so I'd like to ensure I fully understand the context before providing a detailed answer. Additionally, could you elaborate on the context in which this term was used, as it may help me give a more accurate response?
