FAQ Q: What is a Unix timestamp? A: A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It's a standard way to represent time in computing. Q: What date formats are supported? A: Common formats like YYYY-MM-DD HH:MM:SS, MM/DD/YYYY, ISO 8601, and RFC 2822 are all supported. The tool will attempt to parse most standard date formats automatically. Q: Can I convert milliseconds? A: Yes! If you have a timestamp in milliseconds (typically 13 digits), the tool will automatically detect and convert it by dividing by 1000. Q: What's the difference between UTC and Local Time? A: UTC (Coordinated Universal Time) is the world's time standard. Local time is adjusted for your system's timezone. When converting, choose UTC for standardized results or Local for timezone-adjusted times. Q: How many conversions can I do? A: Free users get 25 conversions per day. Pro users get unlimited conversions and access to bulk processing. Q: Is my data stored? A: Pro users have access to conversion history for 90 days. Free users' conversions are not stored permanently. Examples Example 1: Convert Timestamp to Date Input:

Timestamp: 1701450000 Direction: Timestamp → Date Timezone: UTC

Output:

Date: 2023-12-01 15:00:00 UTC ISO 8601: 2023-12-01T15:00:00+00:00 Day of Week: Friday

Example 2: Convert Date to Timestamp Input:

Date: 2025-10-31 14:00:00 Direction: Date → Timestamp Timezone: UTC

Output:

Unix Timestamp: 1730383200 Formatted Date: 2025-10-31 14:00:00 UTC

Example 3: Bulk Conversion CSV Format csvtimestamp_input,direction,timezone 1701450000,to_date,utc 2025-10-31 14:00:00,to_timestamp,local 1609459200,to_date,utc Troubleshooting "Invalid timestamp format" Error Make sure your timestamp is a numeric value without any letters or special characters. "Unable to parse date format" Error Try using a standard format like YYYY-MM-DD HH:MM:SS. The tool supports many formats but may not recognize all variations. Bulk Upload Not Working Ensure your CSV file:

Has the correct headers: timestamp_input, direction, timezone Is properly formatted with no extra columns Doesn't exceed row limits (25 for free, 1000 for Pro)

Results Look Wrong Double-check that you've selected the correct:

Conversion direction (to_date vs to_timestamp) Timezone (UTC vs Local)

If timestamps are 13 digits long, they're likely in milliseconds and will be automatically converted. CSV Format for Bulk Processing For bulk conversions, your CSV file should have these three columns: csvtimestamp_input,direction,timezone 1701450000,to_date,utc 2025-10-31 14:00:00,to_timestamp,local Column Descriptions:

timestamp_input: The value to convert (timestamp or date string) direction: Either "to_date" or "to_timestamp" timezone: Either "utc" or "local"
