What is NTP and why precise time matters for RFC3161
The Network Time Protocol (NTP) is the standard mechanism to synchronize system clocks across networks. For an RFC3161 Timestamp Authority (TSA), accurate and provably-correct system time is fundamental – timestamps are legal and technical proof that a piece of data existed at a particular instant. Even small clock drift or inconsistent time sources can invalidate long-term evidence or trigger RFC3161 timeNotAvailable and related errors. Khatim Timestamp Server treats time integrity as a first-class requirement: it integrates tightly with NTP to ensure timestamp tokens are generated only when the server’s time is reliable and auditable.
"If time can’t be trusted, neither can the timestamp"
How Khatim Timestamp Server integrates with NTP servers
Khatim Timestamp Server (KTS) connects to one or more NTP servers and continuously validates the system clock against configured time sources before issuing RFC3161 tokens. Integration highlights:
-
Support for multiple NTP endpoints (primary + fallbacks) and ordered checks.
-
Optional “check all” mode (verify every configured server) or “first-pass” mode (accept first healthy server).
-
Configurable retry and reconnection strategies for transient network issues.
-
Automatic correlation of NTP health with timestamp engine health (so KTS can mark timeNotAvailable when appropriate).
-
Alerts fired on NTP communication failures and threshold breaches (e.g., NTP_COMM_FAILED, NTP_THRESHOLD_REACHED), enabling early detection of clock-related risk.
Flexible configuration options
KTS exposes practical configuration options so operators can adapt to diverse environments:
-
Acceptable drift (ms): set the maximum allowed offset before a health degradation or hold.
-
Check policy: choose to check all NTP servers or stop on the first successful response.
-
Tiebreak rules: control behavior when pass/fail counts tie across servers.
-
Retry counts and intervals: tune how many attempts KTS makes before marking a source as failed.
-
System clock monitoring: enable continuous background checks and automated holds on signing if drift exceeds limits.
-
Log & retention settings: how long to keep NTP transactions and archival frequency.
These options allow conservative setups for high-assurance environments and more permissive modes for high-availability use cases.
NTP transaction log viewer & statistical graphs – unique monitoring for troubleshooting
Khatim’s built-in NTP Transaction Log Viewer is a one-of-a-kind operational tool designed for TSA operators and auditors. Key capabilities:
-
Per-server telemetry: precision, NTP version, stratum, offset, round-trip time, jitter, reachability and last successful check.
-
Transaction logs: each NTP check is recorded in human-readable form with timestamps, responses and diagnostic codes for forensic review.
-
Statistical dashboards: time-series charts for offset, drift, precision and pass/fail counts (filters: today / 7d / 30d / 365d / custom range).
-
Alert timeline correlation: visually correlate NTP anomalies with RFC3161 errors, HSM events, and timestamp issuance trends to quickly identify root causes.
-
Export & audit: export logs for external auditing, or include NTP evidence in timestamp signing reports to support legal or compliance reviews.

What’s so unique about Khatim Timestamp NTP Integration
Khatim treats time as first-class telemetry not an afterthought. Our NTP integration is purpose-built for Trusted Timestamp Authorities (TSAs) and goes beyond simple clock sync to deliver operational assurance, auditability, and root-cause clarity.
Key differentiators
-
One-of-a-kind NTP Transaction Log Viewer
Every NTP query/response is recorded in readable form (response fields, offsets, stratum, jitter, return codes). This makes time verification usable as forensic evidence not just an error code in a log file. -
Rich statistical dashboards
Time-series charts for offset, drift, reachability and jitter (today / 7d / 30d / 365d / custom). Visualize trends and spot slow degradations long before they cause timestamp failures. -
Policy-driven multi-source validation
Support for primary + fallback NTP servers with configurable modes (check-all, first-pass, tiebreak rules). Khatim lets you balance strict assurance vs high availability per your operational risk profile. -
Automated health controls and signing holds
If clock drift exceeds configured thresholds or NTP checks fail repeatedly, Khatim can automatically pause timestamp issuance and raise high-urgency alerts – preventing issuance of questionable tokens. -
Correlated root-cause analysis
NTP anomalies are visually correlated with RFC3161 errors, HSM events, and issuance trends so admins can quickly answer “did a clock issue, an HSM fault, or a template change cause this?” – all from the same timeline. -
Audit-grade exports & traceability
Export signed NTP transactions (CSV) and include them in timestamping reports to satisfy auditors, courts, or compliance reviews. Every check is timestamped, signed in the audit trail, and retained per your retention policy. -
Flexible ops & integration modes
Tunable drift thresholds, retry policies, log retention, and agent-based collection options (push model for segmented networks). Works with clustered/multi-host TSA setups and integrates with HSM telemetry for full trust stack visibility.
Bottom line: Khatim turns NTP from a hidden single point of failure into an auditable, monitored signal that actively protects timestamp integrity – enabling confident, defensible RFC3161 operations.

Words from Client
Leading companies rely on us for their PKI and digital signature needs
Security is at the heart of our business. We were struggling with our PKI implementation when Codegic came to the rescue. They not only sorted our technical issues but also designed the whole PKI for the infrastructure. There in depth PKI knowledge down to the code level helped us in many ways. I highly recommend their PKI technical expertise.
