time values with period less than delta() found

Dataset -> https://pastebin.com/raw/J0Vre2Fw

In this dataset there are a few columns which represent the AAPL stock price over time.
The first column "statatime" is stored as a Double, it is formatted as format statatime %tcDDmonCCYY_HH:MM:SS.sss

This is the output I get:

. describe statatime

Variable Storage Display Value
name type format label Variable label
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
statatime double %tc..

. tsset statatime, delta(86400 second)

Time variable: statatime, 13jan2020 14:30:00.000 to 03nov2022 13:30:00.000, but with gaps
Delta: 1 day

. tsreport

Time variable: statatime
----------------------------------------
Starting period = 13jan2020 14:30:00.000
Ending period = 03nov2022 13:30:00.000
Number of obs = 710
Number of gaps = 148

. tsfill

. tsreport
time values with period less than delta() found
r(451);

as you will see in the original dataset, there is no statatime column members that do not end with "30:00.000"
thank you for looking

If your data are really daily, the time of day recorded should be trivial and so you could push the times through dofc().

sort statatime 
gen diff =  statatime - statatime[_n-1] 
spikeplot diff

should throw light on what is going on.

Oh I had not realized that the data had daylight savings
