How is Daylight Saving Time (DST) determined?

The engine compares the current UTC offset against standard winter and summer offsets for that specific IANA geographic timezone to determine whether DST is actively observed.

Is bulk log file data sent to external servers?

Never! All bulk log parsing, timestamp extraction, and CSV generation run 100% in local browser memory with 0% server transmission.

Common Questions

Frequently Asked Questions

Standard JavaScript Numbers lose precision beyond 53 bits (approx. 16 digits). Nanosecond epoch timestamps are 19 digits long, so native BigInt arithmetic prevents rounding errors.
