March Synchronizer
Every march lands on the same second.
Exact Exact arithmetic on the values you enter.
How it is calculated
The March Synchronizer tells every player in a group when to send their march so that all of them land on the target in the same second — for rally joins, garrison swaps and coordinated hits in Whiteout Survival.
Take the longest march time in the group, Dmax. Each player leaves Dmax − (their march time) seconds after the first departure. The slowest player leaves first, at offset 0, and everyone arrives at first departure + Dmax.
All arithmetic is in whole seconds. When an offset crosses into the next minute the table says so, so a wrapped second value is never shown without its minute. With a clock time set, departures are shown as real times in UTC or your local time and a countdown follows the next departure using real timestamps, so it stays correct after the phone locks.
Example
Frostbyte 0:45 · Ashvale 0:36 · Kestrel 0:33 · Nordwind 0:33 · Emberline 0:39 Dmax = 45 s Frostbyte :00 · Emberline :06 · Ashvale :09 · Kestrel :12 · Nordwind :12 Everyone lands at :45.
Questions
- Which march time should I enter?
- The travel time the game shows on the march screen for that player to that target, after their speed buffs. Each player must read their own value — distance and buffs differ.
- What if two players have the same march time?
- They leave on the same second. The table marks them so the caller can say both names at once.
- Can I share the plan?
- Copy it as Discord-formatted text, or copy a share link. The link stores the plan in the part of the URL after #, which is never sent to a server.
