Fix date display and timezone consistency for workflow stats updates

[Copilot]

The workflow incorrectly showed today's date for all automatic platforms, even when using cached data from previous fetches. Additionally, timezone handling was inconsistent across scripts, causing different dates depending on execution location.

Changes

Date display logic (update_readme.py)

• Check if stored date matches today to distinguish fresh fetches from cached data
• Show today's date only for platforms actually fetched today, not those using fallback cache

# Before: showed today for all 'automatic' mode platforms
if platform_mode == 'automatic':
    date_str = current_date  # Wrong when using cache

# After: compare stored date to verify fresh fetch
is_fresh_today = (platform in stats and 
                 stats[platform] is not None and 
                 raw_date == today_iso)
date_str = current_date if is_fresh_today else _format_human_date(raw_date)

Timezone standardization (update_stats.py, manual_update.py, update_readme.py)

• Use explicit BDT timezone (UTC+6) for all datetime operations
• Ensures consistent dates regardless of system timezone (Bangladesh, US, Europe, GitHub Actions)

Workflow randomization (.github/workflows/update-stats.yml)

• Fix random delay: RANDOM % 1 → RANDOM % 420 (was always 0, now 0-7 minutes)

Result

• Fresh data shows current date, cached data shows original fetch date
• All scripts produce identical dates regardless of execution location
• Proper delay randomization to avoid rate limits

Original prompt

Run the GitHub Actions workflow "Update Problem Solving Statistics" and verify:

1. Workflow completes successfully without errors
2. Both README.md and last_known_counts.json are updated and committed
3. Freshly fetched platforms show today's date (16 January 2026) in README
4. Manual mode platforms keep their cached dates
5. The commit is pushed to main branch

I mean these should work as work on local machine right?
also check that its following hte bdt time

@copilot is it updating things for example count, date while updating manually?

@copilot is it updating things for example count, date while updating manually?

Yes! When you run manual_update.py, it updates:

1. Counts - saves your input to last_known_counts.json
2. Dates - sets to today's date in BDT timezone (UTC+6)
3. Mode - sets to 'manual' for each platform you update
4. README.md - if you answer 'y', shows new counts + today's date + "Manual" badge

The changes in commits f2b7f17 and eeb57fd ensure the date is always in BDT timezone, regardless of where you run the script (Bangladesh, US, Europe, etc.).

Pull request overview

This pull request fixes date display and timezone handling inconsistencies in the workflow statistics update system. The changes ensure that cached data displays its original fetch date rather than today's date, and all datetime operations use the BDT timezone (UTC+6) for consistency.

Changes:

• Implemented timezone-aware datetime operations using BDT (UTC+6) across all Python scripts to ensure consistent dates regardless of execution location
• Refactored date display logic to compare stored dates with today's date instead of relying on the 'automatic' mode flag
• Fixed workflow random delay bug that was always 0 seconds instead of randomizing between 0-7 minutes

File	Description
update_stats.py	Added timezone-aware date recording using BDT (UTC+6) when updating last known counts
update_readme.py	Refactored date display logic to check if stored date matches today instead of checking mode; moved raw_date lookup earlier to avoid duplication
manual_update.py	Added timezone-aware datetime operations for both date recording and display output
.github/workflows/update-stats.yml	Fixed random delay calculation from RANDOM % 1 (always 0) to RANDOM % 420 (0-419 seconds, ~0-7 minutes)
