Kernel.sigil_T
You're seeing just the macro
sigil_T, go back to Kernel module for more information.
Handles the sigil ~T for times.
By default, this sigil uses the built-in Calendar.ISO, which
requires times to be written in the ISO8601 format:
~T[hh:mm:ss]
~T[hh:mm:ss.ssssss]such as:
~T[13:00:07]
~T[13:00:07.123]If you are using alternative calendars, any representation can be used as long as you follow the representation by a single space and the calendar name:
~T[SOME-REPRESENTATION My.Alternative.Calendar]The lower case ~t variant does not exist as interpolation
and escape characters are not useful for time sigils.
More information on times can be found in the Time module.
