The map below highlights the NST (Newfoundland Standard Time) and CAT (Central Africa Time) timezone regions across the globe.
NST – Newfoundland Standard Time
UTC-03:30Newfoundland Standard Time (NST) is a unique half-hour offset time zone in Canada, 3.5 hours behind UTC.
- •NST is one of only a few half-hour offset time zones in the world.
- •Newfoundland joined Canada in 1949 and kept its unique time zone.
- •St. John's is the easternmost city in North America.
CAT – Central Africa Time
UTC+02:00Central Africa Time (CAT, UTC+02:00) covers Zimbabwe, Zambia, Mozambique, Malawi and neighbouring countries.
- •Central Africa Time is fixed at UTC+02:00 with no daylight saving.
- •CAT matches South Africa Standard Time (SAST) all year.
- •It is the same offset as Central European Time in winter.
- •Harare is level with Johannesburg and one hour ahead of Lagos.
NST to CAT Time Difference – Complete Guide
NST runs on Newfoundland Standard Time (NST) at UTC-03:30. CAT runs on Central Africa Time (CAT) at UTC+02:00. That puts NST 5 hours 30 minutes ahead of CAT — a difference of +5h 30m at the current offsets.
In practice, when it is 9:00 AM in NST it is 2:30 PM in CAT. Midnight in NST is 5:30 AM in CAT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NST to CAT time
- Scheduling a call from NST to CAT: a 10:00 AM start in NST lands at 3:30 PM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both NST and CAT are inside the 9-to-5 working day between 9:00 AM and 11:30 AM NST time (2:30 PM–5:00 PM CAT). That is roughly 2 hours 30 minutes of usable overlap.
- Coordinating a NST-based team with CAT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM NST" is unambiguous; "3 PM" across a +5h 30m gap is not.
- Block 9:00 AM–11:30 AM NST as the recurring meeting window if you work primarily from NST and need CAT colleagues present.
About NST (Newfoundland Standard Time)
Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.
About CAT (Central Africa Time)
Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.
Best time to call between NST and CAT
Both NST and CAT sit inside the 9 AM – 5 PM working day between 9:00 AM–11:30 AM NST, which is 2:30 PM–5:00 PM CAT. That gives roughly 2 hours and 30 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
NST and CAT overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.
NST is 5 hours 30 minutes ahead of CAT (NST UTC-03:30 → CAT UTC+02:00). The shared working window is 9:00 AM–11:30 AM NST. Remember to re-check around daylight-saving transitions.
