  • Table: Current real time in various formats - this table shows current date and time ("real time clock") in different formats. Available formats are:
    • formatted (YYYY.MM.DD HH:MM:SS.ms) - classic, human readable format e.g. 2017-01-12 20:31:10.100,
    • UNIX timestamp (decimal) - number of seconds from 1 January 1970 (begin of UNIX epoch) e.g. 1499790465,
    • UNIX timestamp (hexadecimal) - the same as above (UNIX timestamp, decimal), but converted to hexadecimal number e.g. 0x5964fc81.
