From 38737762c5e3e6343ccb73a1de8562b0f7cdc993 Mon Sep 17 00:00:00 2001 From: "Janus C. H. Knudsen" Date: Fri, 3 Oct 2025 16:05:22 +0200 Subject: [PATCH] Adds technical date and time formatting Adds options for technical date and time formatting and includes the option to show seconds. Updates time formatting to use UTC-to-local conversion and ensures consistent colon separators for time values. Adjusts all-day event handling to preserve original start/end times. --- src/core/CalendarConfig.ts | 29 +++- src/data/mock-events.json | 4 +- src/elements/SwpEventElement.ts | 8 +- src/renderers/EventRenderer.ts | 14 +- src/utils/PositionUtils.ts | 5 +- src/utils/TimeFormatter.ts | 50 +++++- test/utils/TimeFormatter.test.ts | 286 +++++++++++++++++++++++++++++++ 7 files changed, 370 insertions(+), 26 deletions(-) create mode 100644 test/utils/TimeFormatter.test.ts diff --git a/src/core/CalendarConfig.ts b/src/core/CalendarConfig.ts index f6b1155..2602558 100644 --- a/src/core/CalendarConfig.ts +++ b/src/core/CalendarConfig.ts @@ -78,6 +78,8 @@ interface TimeFormatConfig { timezone: string;
