Change the start date and time of an activity, for example when the watch clock was wrong after travel or a reset. Every time in the file moves together, so distance, pace and averages stay the same.
How to use it
Load the file, enter the correct start time in your local time, or use the one-hour and one-day buttons for time zone and date mistakes, then download the corrected file.
Times from 1989
If the activity shows a date in 1989 or 1990, the watch recorded before it knew the time. The repair tool fixes that automatically.
Quick answers
Why does Strava say my file has corrupted time data? Usually some data points carry a 1989 time or jump backwards. Run the file through the repair tool, which fixes both.
Will changing the time affect my records? No. Pace, distance and heart rate are unchanged. Only the date and time move.
