Yeah, it's a weird one.
Here's code to reproduce:
const start = moment.tz('2017-11-01T01:00:00', 'America/Chicago'); const end = moment.tz('2017-11-10T00:55:00', 'America/Chicago'); while (start.isBefore(end)) { start.add(5, 'minutes') .round(5, 'minutes'); this.logger.info(start.format()); }
This will behave as expected, at first:
