Datetime bug
When using django TruncDate, the truncated value looks like this:
2025-02-16T00:00:00-05:51
I have no idea how "05:51" timezone offset is being applied. Why is it like this?
When using Django’s TruncDate, the truncated datetime showed a strange timezone offset: 2025-02-16T00:00:00-05:51. This offset is not a standard timezone, which usually shifts by whole or half hours, never odd minutes like 51.
This weird offset likely comes from the server’s current timezone being interpreted as a historical or non-standard local time, possibly due to outdated or corrupted timezone data. Passing the timezone explicitly using a known standard, like UTC or a proper pytz timezone (e.g., 'America/New_York'), fixes the issue.
The core lesson: never trust automatic timezone guesses when truncating dates in Django. Always specify the timezone explicitly to avoid bizarre offsets and ensure consistent, predictable datetime values.By Mike Morton
