If so, please return something with 4+ digit year, month, day, hour, minute, second and time zone (taken from the computer hosting the adapter). Could be just a string. On Linux the date can take a format string and spit out everything needed. Assume the NABU side will handle localisation of month and day names. Include day of week to avoid some tricky computations. Have both the numeric time zone (so we can calculate UTC time) and time zone name (can't figure it out otherwise and need it for showing the user):
date "+%F %T %z %Z %u"
2024-04-14 19:04:01 -0400 EDT 7
And hey, then someone could write a NABU clock display, one which plays music on the hour
