Clock Diagnostic: Identifying Time Current() Freezes and Step Backwards
Info
The Clock Diagnostic: Identifying Time Current() Freezes and Step Backwards is a Script for MetaTrader 5 that clock diagnostic reads timecurrent() and timelocal() every few seconds for a fixed observation window and reports the two failure modes of the server clock: it freezes when no tick arrives, and it can step backwards after a symbol switch, a reconnection or a tick from another instrument. Inputs: InpSeconds = 60 (observation length), InpStep = 2 (interval between readings, seconds).
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Script works exclusively on MetaTrader 5 (both build 600+ and newer versions).

Frequently Asked Questions
Q: How are scripts different from EAs? A: Scripts execute a single action and then stop; EAs monitor the market and trade continuously.
Q: Can I assign a hotkey to a script? A: Yes, right-click the script in the Navigator, select "Set Hotkey," and define your preferred keyboard shortcut.
Q: Why did my script stop? A: Scripts are designed to stop immediately after finishing their programmed command; this is normal behavior.

Description & Settings
Related: Server Clock Synchronization for MetaTrader - another powerful script for MetaTrader 5 traders.
Clock Diagnostic reads TimeCurrent() and TimeLocal() every few seconds for a fixed observation window and reports the two failure modes of the server clock: it freezes when no tick arrives, and it can step backwards after a symbol switch, a reconnection or a tick from another instrument.Also recommended: Time Variable Conversion Utility - similar script with strong performance on MetaTrader 5.
Inputs: InpSeconds = 60 (observation length), InpStep = 2 (interval between readings, seconds).
The script prints both clocks and their initial difference in seconds and hours, a STEP BACK line each time TimeCurrent() goes back, and a summary: readings taken, seconds advanced by each clock, the longest freeze observed and the number of step-backs, followed by a verdict for the window.
Rule it documents: TimeLocal() for timestamps, dates, day changes and expiry; TimeCurrent() for session hours and comparison with market data.
Limit: it measures only the window it runs in. With the market open and ticks arriving, a 60-second run may show no anomaly; run it with the market closed to see the freeze.
