If you look up the history cards for WHLO Akron, you will see that from the time they moved from 610 to 640 they were licensed as 1 KW, DA-1, LT.  The LT stands for Limited Time.  There is no mention of daytime only operation.  I'm pretty sure you will find the same thing for the other stations that Broadcasting Yearbook listed as (L-xxxx) for years.  In the power listings for the stations in BY, they do not say anything like 5 KW-D, which would indicate that they are licensed as a daytimer.  WJJD was listed as 50 KW, DA-1, LT for years.

KMMJ-AM 750 Grand Island, NE is licensed as “Limited Hours” and I was curious what exactly this meant. I inquired, a search of FCC History/Archived Records was made and yielded this answer:

Way back on September 19, 1968, KMMJ was issued a telegram for presunrise authority to commence operation with its licensed facilities at the local sunrise time of cochannel station WSB, Atlanta.  The authority was conditioned subject to the outcome of a rulemaking proceeding (Dockets 17562, 18023, and 18036) relating to the “status of Class II stations [here KMMJ] assigned to US I-A clear channels.”    
 
Ultimately, the Commission settled on a 500 watt limitation on presunrise operation nationwide.  That was less than KMMJ’s regular operating power (10.5 kW directional away from WSB).   It appears too that WSB opposed letting KMMJ keep the higher power presunrise authority (see paragraphs 31 and 32 at  https://docs.fcc.gov/public/attachments/FCC-69-844A1.pdf , July 29, 1969).
 
The solution the staff came up with was to issue the license for KMMJ with “limited time” of operation.  In effect that replaced operation of the 500 watt presunrise limit applicable elsewhere in the country.  See the Memorandum of June 12, 1974:  https://apps2int.fcc.gov/admin/api/download/attachment/25076f9170b21d4a0170bfdedcc90169 .
 
The changes on the license were included on the next renewal of license authorization (BR-676, dated May 20, 1977).  The changes made KMMJ into a “Limited Hours” station and specified the on-air times.  As a practical matter, however, KMMJ continued to operate unchanged.    (This is the origin of the comment in the AM Query:  LIMITED TIME OPERATION: SEE BR-676, MAY 20, 1977.)  BR-676:  https://enterpriseefiling.fcc.gov/dataentry/api/download/attachment/25076f9170b21d4a0170c009b0480176

KMMJ is still licensed to operate in this manner.
 It is likely that there is no other station in the country licensed in this manner.

KBS Seoul Spanish tests to Latin AM.
On which days tests planned ?
Nothing noted on 7430 kHz at around 01.00 UT today March 12.
These KBS tests series are organized and published somehow amateurishly.
Only strange technician engineering test noted from
AGM United States Agency for Global Media (USAGM) Greenville B center
on next door channel 7435 kHz R Marti program
from crash start at 01.53:57 UT, S=8 or -78dBm strength here
in Germany and Switzerland remote SDR rxs.
Program lasted only 6 minutes !
and Greenville signal switched OFF at exact 02.00 UT, on March 12.

ps. reliable direction finding on KiwiNet worldwide, you need at least 
   3-4 powerful and un-disturbed QRM free Kiwi signals for
