Timezone converter
TMT to GMT currently uses Turkmenistan Time in Asia/Ashgabat and Greenwich Mean Time in Europe/London as the live reference pair, with a -4h live gap. TMT to GMT matters whenever Ashgabat and London need to coordinate across a -4h gap. The TMT side covers Turkmenistan, while GMT covers United Kingdom and Ivory Coast — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
Last updated Apr 30, 2026. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.

Based on the busiest city and zone usage found in the current dataset.
TMT (Ashgabat, +05:00) to GMT (London, +01:00) is currently a -4h conversion. Live coverage on the TMT side is anchored by Ashgabat, Türkmenabat, Daşoguz, and Mary; the GMT side draws from London, Abidjan, Bamako, and Dakar.
TMT to GMT matters whenever Ashgabat and London need to coordinate across a -4h gap. The TMT side covers Turkmenistan, while GMT covers United Kingdom and Ivory Coast — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
This pair runs between Europe or Africa and Asia or the Pacific. With -4h between them, the late European morning often catches the early Asian evening, which is the practical window for cross-region operations and travel planning.
GMT follows seasonal clock changes through Europe/London, while TMT stays on a fixed offset year-round. The result is a gap that quietly shifts by an hour twice a year — short by an hour in winter (or summer, depending on hemisphere) and back to normal afterwards.
TMT and GMT sit exactly 4h apart, with about 4h of shared 9-to-5 time. That is enough room for one daily standup plus one focused working session, which is what most cross-region teams actually use this overlap for.
TMT coverage on this page is led by Ashgabat, Turkmenistan, Türkmenabat, Turkmenistan, Daşoguz, Turkmenistan, and Mary, Turkmenistan, with 2 more in the live dataset. That mix is what makes TMT feel anchored to South and Southeast Asian business hubs in practice rather than just an abbreviation on a chart.
GMT coverage is led by London, United Kingdom, Abidjan, Ivory Coast, Bamako, Mali, and Dakar, Senegal, with 2 more anchoring the wider label family. Combined with the TMT side, this conversion ends up describing Europe-to-Asia trade calls, manufacturing supply-chain coordination, and joint-venture standups.
