The invention discloses a method and system for solving time zone delay in a cross-border fund collection set, and the method comprises the steps: generating the optimal collection instruction triggering time of a transnational branch company through a working time intersection algorithm and a daylight saving time adaptive UTC time difference dynamic calculation rule, and carrying out the fund collection operation based on the optimal collection instruction triggering time. Collection delay caused by time zone dislocation can be avoided; meanwhile, data synchronization after collection is carried out by means of a dual-mode data synchronization mechanism and a time synchronization mechanism based on a UTC time difference dynamic calculation rule, the problem of flow stagnation caused by inconsistency of cross-time zone data can be eliminated, the time difference calculation rule is dynamically adjusted based on daylight saving time and non-daylight saving time, time conversion errors can be avoided, and the time conversion efficiency is improved. In addition, the cross-time-zone manual guarding is not needed, the risk of manual errors is avoided, and the labor cost is remarkably reduced.

The invention provides a global task scheduling method and system of a time-aware state machine based on event triggering. The method comprises the following steps: in response to the fact that physical time reaches a preset logic time boundary, generating a logic time vector comprising a time vector and a logic time index; submitting the logic time vector to a distributed consensus engine to make system nodes reach a consensus and form a consensus logic time vector; and taking the consensus logic time vector as input, driving a time sensing state machine corresponding to the task to perform state transition, and triggering task execution when the state transition is performed to an execution state. According to the method, variable physical time calculation and stable logic state decision are decoupled, global logic time is synchronized through a consensus mechanism, the problem of scheduling inconsistency caused by daylight saving time and time zone rule change in cross-time zone and cross-region environments is fundamentally solved, and the method has natural immunity for time anomalies such as disappearance time and repetition time.

A method, computer program product, and computer system for scheduling electronic meetings. A time zone table including a plurality of local time zones is provided. The time zone table includes a plurality of specified dates and an offset from Coordinated Universal Time (UTC) for each of the plurality of local time zones, and for each date the offset from UTC for each time zone includes an adjustment for daylight savings time or no adjustment for daylight savings time. An electronic meeting request for a plurality of users having a plurality of electronic calendars is provided. A primary time zone and a secondary time zone are also provided. The secondary time zone is different from the primary time zone. A primary time zone start time of the meeting request and a secondary time zone start time of the meeting request are determined using the time zone table.

The purpose of the present application is to provide a method and device for verifying the switching of summer and winter time, which realizes the embedding of the traditional verification logic depending on external test tools and manual intervention into the firmware runtime system of the device, and constructs a closed-loop summer time DST self-verification mechanism with the capabilities of rule analysis, event pre-play, execution monitoring, result comparison and abnormal response. The mechanism does not depend on network connection or external debugging interface, and can still complete the integrity check of the DST switching behavior independently when the device is in a completely offline state, thereby solving the problems of time confusion, data distortion and service interruption caused by the lack of self-checking capability in the prior art.

The purpose of this application is to provide a continuous recording method and device based on winter / summer time switching. By introducing a monotonically increasing logical clock (MLC) decoupled from physical time, constructing a dynamically updated time mapping table, and implementing a dual timestamp metadata embedding strategy of physical time and monotonically increasing MLC, and using time mapping table-based retrieval logic, this method systematically solves the technical problems faced by existing surveillance recording devices in winter / summer time switching scenarios, such as recording loss, duplication, retrieval failure, and time misalignment. This application does not rely on specific operating system features and can be implemented on general embedded Linux or RTOS platforms, exhibiting high engineering feasibility and product compatibility.
