GMT到TMT轉換器.

GMT (London, +01:00) to TMT (Ashgabat, +05:00) is currently a +4h conversion. Live coverage on the GMT side is anchored by London, Abidjan, Bamako, and Dakar; the TMT side draws from Ashgabat, Türkmenabat, Daşoguz, and Mary.

GMT to TMT matters whenever London and Ashgabat need to coordinate across a +4h gap. The GMT side covers United Kingdom and Ivory Coast, while TMT covers Turkmenistan — 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. That asymmetry is the real differentiator on this page: the gap widens or narrows by an hour twice a year, so calendar invites scheduled in one season often look wrong in the other.

GMT and TMT 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.
