It also accepts an optional separator argument to separate the time units.

const milliseconds = 5000000;

theNextDayOn

This function returns the milliseconds timestamp of the next day. It takes an optional dayOffset argument to calculate the timestamp for a specific number of days in the future.

const nextDayTimestamp = tools.time.theNextDayOn(1);
