I have some kind of smart home on multiple esp8266, and I periodically update code of their firmwares via OTA.
And sometimes I forget to upload actual code on them. For example, I don't remember, if I uploaded a new version of firmware to esp8266, that serves in toilet .
Each of esp8266 firmware is *.bin file, if I understood it correctly. Each of file has time of creation.
And question is - does esp8266 stores date and time of firmware, uploaded via OTA (or update) and is there any Arduino program method to get that date and time?
