Timing and Sessions backend framework

Timing_Library — Timing Utilities (Pine v6)

Purpose
A lightweight timing toolkit for indicator development. It parses session strings, returns start/stop timestamps for the current day, and resolves a UTC offset for common TradingView time zones. The library itself does not draw, alert, or place trades and must be called by a parent indicator.

Core Functions
- extractHourMinute(sessionInput): Parses "HHMM" into [hour, minute].
- ExtractStartStopTimestamp(sessionInput): Accepts "HHMM-HHMM" and returns [sessionStartTime, sessionEndTime] for the current date.
- GetUTCOffset(): Maps syminfo.timezone to an integer UTC offset (hours), with fallback parsing for UTC± patterns.

Key Notes
- Backend-only helper library: no signals, no alerts, no order execution.
- Designed for educational, research, and indicator-development purposes.
- No external data requests and no user data handling.
- Time zone handling is best-effort; behavior may vary with regional DST rules.

Usage
1) Import this library into your indicator.
2) Provide session inputs like "0930-1030" to ExtractStartStopTimestamp for same-day timestamps.
3) Use GetUTCOffset to align session logic or convert between local and exchange time where needed. Visualization and alerting remain in the parent script.
