Timestamps
Particularly when you want to use some of the synchronization features, first make sure that WinSCP will be able to convert timestamps from local conventions to remote server conventions and vice versa.
There are several factors that affect conversion and interpretation of the timestamps:
| Factor | Symptom |
|---|---|
| Daylight saving time (DST) | Timestamps of some files are shifted by one hour. |
| Server timezone offset | Timestamps of all files are shifted by the same time span. Only SCP protocol is affected. |
| Local file system is FAT | File timestamp is always rounded to the next even second. This is property of old FAT filesystem. For the reason WinSCP ignores 1-second time difference with all its synchronization features. Note that FAT is used rarely nowadays, mostly with removable medias only. |

Also note that for WinSCP to try to convert file timestamp at all, you need to have transfer option Preserve timestamp enabled.
