The phrase 'จนถึงเวลา (jon thʉ̌ng welaa)' is used in Thai language to indicate an action or event that will continue up to a certain point in time, or a condition that remains in place until a particular time. It is often used to link two clauses, with the event in the second clause occurring when the time specified in the first clause is reached. The first clause refers to the ongoing action or state, and the second clause refers to the event or action that will take place when the specified time comes.
