Use when a session boundary or scheduled job is expressed in exchange-local time and daylight saving shifts it; resolves local boundaries to UTC across zones and flags skipped and repeated wall-clock times.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## When to Use Use this skill in global market data pipelines, cross-border relative-value algorithms, and session schedulers spanning US (NYSE/Nasdaq), European (LSE/XETRA), and Asian (TSE/HKEX) exchanges — anywhere a session boundary, a cron trigger, or a bar-aggregation boundary is expressed in exchange-local time and consumed in UTC. Two statutory rules drive the behaviour, and they do not line up: - **US** — DST runs from 02:00 **local** time on the second Sunday of March to 02:00 local on the first Sunday of November (15 U.S.C. § 260a, as amended by the Energy Policy Act of 2005). Because the rule is stated in local time, US zones transition an hour apart from each other (Eastern before Central, and so on). - **EU** — summer time runs from 01:00 **GMT** on the last Sunday of March to 01:00 GMT on the last Sunday of October (Directive 2000/84/EC, Arts. 2–3). Because the rule is stated in GMT, every Member State transitions at the same instant. The mismatch produces two **desynchronization windows** each year, during which the transatlantic overlap shifts by one hour. Their lengths are **not** fixed: | Window | Boundaries | Length | |---|---|---| …

How to install
mdr add himanshuj16/algo-trading-skills/daylight-saving-time-transition-handling@sha256:0925af7fdc709c86The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
