From 3390449aa68673e689b9a779d11dfbe4033ce57a Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" <41898282+github-actions[bot]@users.noreply.github.com> Date: Thu, 23 Apr 2026 15:43:32 +0000 Subject: [PATCH 1/6] fix: standardize timestamps to DateTimeOffset UTC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace DateTime.Now/DateTime.UtcNow with DateTimeOffset.UtcNow across all timestamp fields in ChatMessage, ToolActivity, PendingOrchestration, ReflectionCycle, AgentSessionInfo, ActiveSessionEntry, and SessionSummary. Key changes: - ChatMessage.Timestamp: DateTime → DateTimeOffset - All 10 ChatMessage factory methods use DateTimeOffset.UtcNow - ToolActivity.StartedAt/CompletedAt: DateTime → DateTimeOffset - PendingOrchestration.StartedAt: DateTime → DateTimeOffset - ReflectionCycle timestamps: DateTime? → DateTimeOffset? - AgentSessionInfo.CreatedAt: DateTime → DateTimeOffset - Remove ToLocalTime() workarounds in dispatch/resume paths - UI display uses .LocalDateTime.ToShortTimeString() - ChatDatabase boundary: DateTimeOffset ↔ DateTime for SQLite - 6 new behavioral tests for UTC standardization Not changed (by design): - AgentSessionInfo.LastUpdatedAt/ProcessingStartedAt (Interlocked ticks) - ScheduledTask timestamps (separate concern, local time intentional) Fixes #386 Co-authored-by: copilot-agentic-workflow[bot] <224017+copilot-agentic-workflow[bot]@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- PolyPilot.Console/Models/AgentSession.cs | 10 +-- PolyPilot.Tests/AgentSessionInfoTests.cs | 2 +- PolyPilot.Tests/ChatMessageTests.cs | 86 ++++++++++++++++--- .../ConsecutiveStuckSessionTests.cs | 4 +- PolyPilot.Tests/ContinuationTests.cs | 18 ++-- PolyPilot.Tests/ModelSelectionTests.cs | 2 +- PolyPilot.Tests/MultiAgentRegressionTests.cs | 27 +++--- .../OrchestrationPromptDisplayTests.cs | 2 +- PolyPilot.Tests/OrphanedWorkerScanTests.cs | 18 ++-- PolyPilot.Tests/ReflectionCycleTests.cs | 6 +- PolyPilot.Tests/RemoteModeTests.cs | 6 +- PolyPilot.Tests/ResponseFlushTests.cs | 50 +++++------ PolyPilot.Tests/SessionOrganizationTests.cs | 2 +- PolyPilot.Tests/SteeringMessageTests.cs | 6 +- PolyPilot/Components/ChatMessageItem.razor | 4 +- PolyPilot/Models/AgentSessionInfo.cs | 2 +- PolyPilot/Models/BridgeMessages.cs | 2 +- PolyPilot/Models/ChatMessage.cs | 32 +++---- PolyPilot/Models/ReflectionCycle.cs | 22 ++--- PolyPilot/Services/ChatDatabase.cs | 4 +- PolyPilot/Services/CopilotService.Bridge.cs | 6 +- PolyPilot/Services/CopilotService.Events.cs | 8 +- .../Services/CopilotService.Organization.cs | 24 +++--- .../Services/CopilotService.Persistence.cs | 4 +- .../Services/CopilotService.Providers.cs | 6 +- .../Services/CopilotService.Utilities.cs | 4 +- PolyPilot/Services/CopilotService.cs | 10 +-- PolyPilot/Services/DemoService.cs | 2 +- PolyPilot/Services/ExternalSessionScanner.cs | 4 +- 29 files changed, 217 insertions(+), 156 deletions(-) diff --git a/PolyPilot.Console/Models/AgentSession.cs b/PolyPilot.Console/Models/AgentSession.cs index 6f4b62ddc4..58f5c11fa9 100644 --- a/PolyPilot.Console/Models/AgentSession.cs +++ b/PolyPilot.Console/Models/AgentSession.cs @@ -3,13 +3,13 @@ namespace PolyPilot.Models; -public record ChatMessage(string Role, string Content, DateTime Timestamp); +public record ChatMessage(string Role, string Content, DateTimeOffset Timestamp); public class AgentSession : IAsyncDisposable { public string Name { get; } public string Model { get; } - public DateTime CreatedAt { get; } + public DateTimeOffset CreatedAt { get; } public List History { get; } = new(); public bool IsProcessing { get; private set; } public string?
