Greenwich Mean Time (GMT), Coordinated Universal Time (UTC), or Zulu time (which is equivalent to UTC) is critical in cybersecurity for several reasons:

Incident Response: During a cyber incident, accurate and synchronised timestamps are critical for understanding the sequence of events, identifying the source of the breach, and taking necessary action. Cybersecurity teams may be spread across multiple time zones, so a universal time standard can help ensure everyone is on the same page.

Log Correlation: Logs are a critical component of any security infrastructure. They provide information about what's happening across the network and can help identify malicious activity. Log timestamps need to be synchronised, and correlation and analysis can be significantly more difficult when they are not. Using a universal time standard like UTC ensures all logs are consistent, regardless of where or when they are generated.

Forensics: In a cybersecurity investigation, it's essential to know when events occurred in relation to each other. This relationship is crucial when determining the source of an attack, identifying what systems were compromised, and when the incident occurred. Again, this is much easier if all systems use the same time standard.

Regulation Compliance: Some regulations, like those for the financial industry or for protecting personal data (like GDPR), require precise and synchronised timestamps. Using a universal standard like UTC can help ensure compliance.

Collaboration: It's much simpler to coordinate activities and synchronise actions using a universal time standard for multinational companies or those that use cloud-based services in different time zones. Accurate time articulation also applies to communication with third parties, such as law enforcement or other organisations, in case of a cybersecurity incident.
