Note:

• Maintenance Shutdown Planning: Perfect for scheduling utility shutdowns, backup DG run durations, or electrical substation breaker maintenance slots down to the exact second.
• Concrete Curing Tracking: Track concrete curing windows or set test schedules by adding continuous hour parameters (such as standard **72-hour or 168-hour** wet-curing profiles) directly to casting logs.
• Precision Logging: Calculations adhere strictly to ISO standards, performing calculations in clean unix seconds to prevent timezone anomalies.
