Understanding Unix Epoch Timestamps
Clear resolution between seconds, milliseconds, UTC, and local browser offsets.
Seconds vs Milliseconds
Standard POSIX seconds have 10 digits (e.g. 1700000000), while JavaScript and Java epoch timestamps have 13 digits in milliseconds. PicoFix automatically identifies the magnitude or allows manual override.
Zero Timezone Confusion
Timezone discrepancies cause subtle database and logging bugs. PicoFix presents ISO 8601, UTC RFC-2822, and Local Timezone strings side-by-side with clear labeling.
Negative Epoch Support
Historical records and birthdates before January 1, 1970 use negative Unix integers. PicoFix converts negative timestamps seamlessly back to pre-1970 calendar dates.
