time2unixts(1) General Commands Manual time2unixts(1) NAME time2unixts -- converts date/time strings to Unix timestamps SYNOPSIS time2unixts [-T time_format_template | --template time_format_template] [-F | --float] [-I | --integer-decimal] [-X | --integer-hexadecimal] [-0 | --integer-0x-hexadecimal] [-H | --human-readable] [-s | --seconds] [-m | --milliseconds] [-u | --microseconds] [-n | --nanoseconds] time_string [...] time2unixts [-h | --help] time2unixts [-v | --version] DESCRIPTION time2unixts converts date/time strings in the format %Y-%m-%d %H:%M:%S in UTC to Unix timestamps, which is the time (nanoseconds, microseconds, mil- liseconds, or seconds) since the Unix Epoch, i.e. January 1, 1970, 00:00:00.000000000 UTC. ARGUMENTS The following options are available: time_string ... The date/time strings to be converted, as %Y-%m-%d %H:%M:%S[.SSSSSSSSS]. The seconds part may be fractional; the frac- tion is optional. If no date/time string is provided, the current system time is used. -T time_format_template | --template time_format_template Sets the template for parsing the date/time strings. Default is ""%Y-%m-%d %H:%M:%S". The formatting is according to strptime(). See strptime(3) for details. -F | --float Print the Unix timestamp as a floating-point number. -I | --integer-decimal Print the Unix timestamp as a decimal integer number. This is the default. -X | --integer-hexadecimal Print the Unix timestamp as a hexadecimal integer number. -0 | --integer-0x-hexadecimal Print the Unix timestamp as a hexadecimal integer number, prefixed by 0x. -H | --human-readable Provide the output in human-readable form. Default: off. -s | --seconds The Unix timestamp is printed in seconds. Default is in nanosec- onds. -m | --milliseconds The Unix timestamp is printed in milliseconds. Default is in nanoseconds. -u | --microseconds The Unix timestamp is printed in microseconds. Default is in nanoseconds. -n | --nanoseconds The Unix timestamp is printed in nanoseconds. This is the default. -h | --help Prints the program's command-line parameters and exits. -v | --version Prints the program version and exits. EXIT STATUS The time2unixts tool exits with 0 on success, and >0 in case of an error.
