Hex timestamp to date

Hex for 1700000768, read as seconds since the Unix epoch.

Timestamps show up in hex all the time: packet captures, registry values, embedded-device dumps, git internals, and debugger output. An 8-digit hex value like 0x6553f400 is usually 32-bit Unix seconds; 11 digits is typically milliseconds. Paste one below (with or without the 0x) and parsetime converts it and tells you which unit it inferred.

Common questions

How do I know if a hex timestamp is seconds or milliseconds?
By size: 8 hex digits (fits in 32 bits) is almost always seconds, and 11 hex digits is milliseconds for current dates. parsetime infers the unit from the decoded magnitude and says which it chose.
How do I convert hex to a date on the command line?
date -r $((16#6553f400)) on macOS, or date -d @$((16#6553f400)) on Linux. The $((16#…)) form converts hex to decimal in bash.
What is 0xFFFFFFFF as a date?
February 7, 2106, at 06:28:15 UTC. It's the largest value an unsigned 32-bit seconds field can hold. (The signed version caps out earlier, at 0x7FFFFFFF, which is the Year 2038 problem.)
